更新時(shí)間：2018年01月24日 11:55:34 作者：梧桐那時(shí)雨

靜默安裝就是無(wú)聲無(wú)息的在后臺(tái)安裝apk，沒(méi)有任何界面提示。智能安裝就是有安裝界面，但全部是自動(dòng)的，不需要用戶(hù)去點(diǎn)擊。下面腳本之家小編給大家介紹下Android 靜默安裝和智能安裝的實(shí)現(xiàn)方法，感興趣的朋友一起看看吧

1 簡(jiǎn)介

最近研究了Android的靜默安裝和智能安裝，于是寫(xiě)博客記錄一下。靜默安裝就是無(wú)聲無(wú)息的在后臺(tái)安裝apk，沒(méi)有任何界面提示。智能安裝就是有安裝界面，但全部是自動(dòng)的，不需要用戶(hù)去點(diǎn)擊。

首先強(qiáng)調(diào)兩點(diǎn)：靜默安裝必須要root權(quán)限智能安裝必須要用戶(hù)手動(dòng)開(kāi)啟無(wú)障礙服務(wù)

2 原理

靜默安裝、卸載的原理就是利用pm install命令來(lái)安裝apk，pm uninstall 來(lái)卸載apk. 智能安裝是利用android系統(tǒng)提供的無(wú)障礙服務(wù)AccessibilityService，來(lái)模擬用戶(hù)點(diǎn)擊，從而自動(dòng)安裝.

3 pm命令介紹

(1) pm install

pm install 命令的用法及參數(shù)解釋如下:

<code class="hljs haml">pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH
Options:
 -l: install the package with FORWARD_LOCK.
 -r: reinstall an exisiting app, keeping its data.
 -t: allow test .apks to be installed.
 -i: specify the installer package name.
 -s: install package on sdcard.
 -f: install package on internal flash.</code>

(2) pm uninstall

pm uninstall 命令的用法及參數(shù)解釋如下:

<code class="hljs livecodeserver">pm uninstall [-k] PACKAGE
Options:
 -k: keep the data and cache directories around.</code>

上面英語(yǔ)很簡(jiǎn)單，不解釋了.

4 靜默安裝

為了方便演示，我把愛(ài)奇藝的安裝包重命名為test.apk后放在了sdcard上。你可以自己去愛(ài)奇藝官網(wǎng)去下載，也可以自己找一個(gè)apk放到sdcard上，但是要知道apk的包名，后面卸載的時(shí)候要用到。

先上代碼：

<code class="hljs cs">//靜默安裝
 private void installSlient() {
 String cmd = "pm install -r /mnt/sdcard/test.apk";
 Process process = null;
 DataOutputStream os = null;
 BufferedReader successResult = null;
 BufferedReader errorResult = null;
 StringBuilder successMsg = null;
 StringBuilder errorMsg = null;
 try {
  //靜默安裝需要root權(quán)限
  process = Runtime.getRuntime().exec("su");
  os = new DataOutputStream(process.getOutputStream());
  os.write(cmd.getBytes());
  os.writeBytes("\n");
  os.writeBytes("exit\n");
  os.flush();
  //執(zhí)行命令
  process.waitFor();
  //獲取返回結(jié)果
  successMsg = new StringBuilder();
  errorMsg = new StringBuilder();
  successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
  errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));
  String s;
  while ((s = successResult.readLine()) != null) {
  successMsg.append(s);
  }
  while ((s = errorResult.readLine()) != null) {
  errorMsg.append(s);
  }
 } catch (Exception e) {
  e.printStackTrace();
 } finally {
  try {
  if (os != null) {
   os.close();
  }
  if (process != null) {
   process.destroy();
  }
  if (successResult != null) {
   successResult.close();
  }
  if (errorResult != null) {
   errorResult.close();
  }
  } catch (Exception e) {
  e.printStackTrace();
  }
 }
 //顯示結(jié)果
 tvTest.setText("成功消息：" + successMsg.toString() + "\n" + "錯(cuò)誤消息: " + errorMsg.toString());
 }</code>

這段代碼就是在程序中執(zhí)行pm命令，和在adb下執(zhí)行 pm install -r /mnt/sdcard/test.apk 效果是一樣的, 關(guān)鍵的代碼是 Runtime.getRuntime().exec(“su”) ，這段代碼會(huì)要求獲取root權(quán)限，所以你的手機(jī)必須root，不想root的話，直接用模擬器也可以。

通過(guò) Runtime.getRuntime().exec(“su”) 獲取到 process 對(duì)象后就可以寫(xiě)入命令了，每寫(xiě)入一條命令就要換行，寫(xiě)入 ‘\n' 即可，最后寫(xiě)入exit后離開(kāi)命令執(zhí)行的環(huán)境.

5 靜默卸載

靜默卸載和靜默安裝是一樣的，只是命令不同，靜默卸載需要用到包名，同樣，靜默卸載也需要root權(quán)限
看代碼：

<code class="hljs java">//愛(ài)奇藝apk的包名
private static final String PACKAGE_NAME = "com.qiyi.video";
//靜默卸載
 private void uninstallSlient() {
 String cmd = "pm uninstall " + PACKAGE_NAME;
 Process process = null;
 DataOutputStream os = null;
 BufferedReader successResult = null;
 BufferedReader errorResult = null;
 StringBuilder successMsg = null;
 StringBuilder errorMsg = null;
 try {
  //卸載也需要root權(quán)限
  process = Runtime.getRuntime().exec("su");
  os = new DataOutputStream(process.getOutputStream());
  os.write(cmd.getBytes());
  os.writeBytes("\n");
  os.writeBytes("exit\n");
  os.flush();
  //執(zhí)行命令
  process.waitFor();
  //獲取返回結(jié)果
  successMsg = new StringBuilder();
  errorMsg = new StringBuilder();
  successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
  errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));
  String s;
  while ((s = successResult.readLine()) != null) {
  successMsg.append(s);
  }
  while ((s = errorResult.readLine()) != null) {
  errorMsg.append(s);
  }
 } catch (Exception e) {
  e.printStackTrace();
 } finally {
  try {
  if (os != null) {
   os.close();
  }
  if (process != null) {
   process.destroy();
  }
  if (successResult != null) {
   successResult.close();
  }
  if (errorResult != null) {
   errorResult.close();
  }
  } catch (Exception e) {
  e.printStackTrace();
  }
 }
 //顯示結(jié)果
 tvTest.setText("成功消息：" + successMsg.toString() + "\n" + "錯(cuò)誤消息: " + errorMsg.toString());
 }</code>

和靜默安裝一樣的代碼就不解釋了。還有，如果你不知道一個(gè)apk的包名，那么請(qǐng)反編譯后去看AndroidManifest.xml文件，如果這個(gè)文件打開(kāi)全是亂碼，說(shuō)明是被混淆過(guò)的，那么直接安裝它，然后到/data/data下面去找它的包，當(dāng)然，手機(jī)得root才能進(jìn)/data/data目錄。

6 智能安裝

智能安裝就稍微麻煩點(diǎn)了，原理是用到了android提供的AccessibilityService服務(wù)，這個(gè)服務(wù)可以獲取屏幕上的節(jié)點(diǎn)，一個(gè)節(jié)點(diǎn)也就是一個(gè)view，我們寫(xiě)的xml文件中每個(gè)標(biāo)簽就是一個(gè)節(jié)點(diǎn)，然后可以模擬用戶(hù)的操作，對(duì)這些節(jié)點(diǎn)進(jìn)行點(diǎn)擊、滑動(dòng)等操作。我們就是利用這個(gè)原理，來(lái)自動(dòng)點(diǎn)擊安裝按鈕的，當(dāng)然使用這個(gè)服務(wù)必須用戶(hù)手動(dòng)開(kāi)啟無(wú)障礙服務(wù)。下面我們來(lái)看具體的實(shí)現(xiàn)方法。

(1) 創(chuàng)建AccessibilityService配置文件

在res目錄下創(chuàng)建xml目錄，然后在xml目錄下創(chuàng)建一個(gè)accessibility_service_config.xml文件，內(nèi)容如下
res/xml/accessibility_service_config.xml:

<code class="hljs xml" data-filtered="filtered"></accessibility-service></code>

accessibilityEventTypes:指定我們?cè)诒O(jiān)聽(tīng)窗口中可以模擬哪些事件，typeAllMask表示所有的事件都能模擬.

accessibilityFeedbackType:指定無(wú)障礙服務(wù)的反饋方式.

canRetrieveWindowContent:指定是否允許我們的程序讀取窗口中的節(jié)點(diǎn)和內(nèi)容，當(dāng)然是true.

description: 當(dāng)用戶(hù)手動(dòng)配置服務(wù)時(shí)，會(huì)顯示給用戶(hù)看.

packageNames: 指定我們要監(jiān)聽(tīng)哪個(gè)應(yīng)用程序下的窗口活動(dòng)，這里寫(xiě)com.android.packageinstaller表示監(jiān)聽(tīng)Android系統(tǒng)的安裝界面。

其余參數(shù)照寫(xiě)即可。

res/strings.xml:

<code class="hljs xml"><resources>
 <string name="app_name">SlientInstallTest</string>
 <string name="desc">智能安裝app功能演示</string>
</resources></code>

(2) 創(chuàng)建AccessibilityService服務(wù)

<code class="hljs java">public class MyAccessibilityService extends AccessibilityService {
 private static final String TAG = "[TAG]";
 private Map<integer, boolean=""> handleMap = new HashMap<>();
 @Override
 public void onAccessibilityEvent(AccessibilityEvent event) {
 AccessibilityNodeInfo nodeInfo = event.getSource();
 if (nodeInfo != null) {
  int eventType = event.getEventType();
  if (eventType == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED || eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
  if (handleMap.get(event.getWindowId()) == null) {
   boolean handled = iterateNodesAndHandle(nodeInfo);
   if (handled) {
   handleMap.put(event.getWindowId(), true);
   }
  }
  }
 }
 }
 @Override
 public void onInterrupt() {
 }
 //遍歷節(jié)點(diǎn)，模擬點(diǎn)擊安裝按鈕
 private boolean iterateNodesAndHandle(AccessibilityNodeInfo nodeInfo) {
 if (nodeInfo != null) {
  int childCount = nodeInfo.getChildCount();
  if ("android.widget.Button".equals(nodeInfo.getClassName())) {
  String nodeCotent = nodeInfo.getText().toString();
  Log.d(TAG, "content is: " + nodeCotent);
  if ("安裝".equals(nodeCotent) || "完成".equals(nodeCotent) || "確定".equals(nodeCotent)) {
   nodeInfo.performAction(AccessibilityNodeInfo.ACTION_CLICK);
   return true;
  }
  }
  //遇到ScrollView的時(shí)候模擬滑動(dòng)一下
  else if ("android.widget.ScrollView".equals(nodeInfo.getClassName())) {
  nodeInfo.performAction(AccessibilityNodeInfo.ACTION_SCROLL_FORWARD);
  }
  for (int i = 0; i < childCount; i++) {
  AccessibilityNodeInfo childNodeInfo = nodeInfo.getChild(i);
  if (iterateNodesAndHandle(childNodeInfo)) {
   return true;
  }
  }
 }
 return false;
 }
}</integer,></code>

當(dāng)進(jìn)入apk安裝界面就會(huì)回調(diào)onAccessibilityEvent()這個(gè)方法，我們只關(guān)心TYPE_WINDOW_CONTENT_CHANGED和TYPE_WINDOW_STATE_CHANGED兩個(gè)事件，為了防止重復(fù)處理事件，用一個(gè)map來(lái)過(guò)濾事件，后面遞歸遍歷節(jié)點(diǎn)，找到'安裝' ‘完成' ‘確定' 的按鈕，就點(diǎn)擊，由于安裝界面需要滾動(dòng)一下才能出現(xiàn)安裝按鈕，所以遇到ScrollView的時(shí)候就滾動(dòng)一下.

(3) 在AndroidManifest中配置服務(wù)

<code class="hljs xml"><uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE">
  <intent-filter>
  <category android:name="android.intent.category.LAUNCHER">
  </category></action></intent-filter>
 </activity>
 <service android:label="智能安裝App" android:name=".MyAccessibilityService" android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
  <intent-filter>
  </action></intent-filter>
  <meta-data android:name="android.accessibilityservice" android:resource="@xml/accessibility_service_config">
 </meta-data></service>
 </application></uses-permission></code>

重點(diǎn)是后面的service標(biāo)簽:

android:label：這個(gè)就是用戶(hù)看到的無(wú)障礙服務(wù)的名稱(chēng)

android:permission: 需要用到BIND_ACCESSIBILITY_SERVICE這個(gè)權(quán)限.

action: android.accessibilityservice.AccessibilityService 有了這個(gè)action，用戶(hù)才能在設(shè)置里面看到我們的服務(wù)，否則用戶(hù)無(wú)法開(kāi)啟我們寫(xiě)的服務(wù)，也就不能進(jìn)到我們寫(xiě)的MyAccessibilityService里面了.所以，注意不要寫(xiě)錯(cuò)了，如果你發(fā)現(xiàn)無(wú)障礙服務(wù)里面沒(méi)有我們寫(xiě)的服務(wù)，請(qǐng)檢查這里.

(4) 調(diào)用智能安裝代碼

前面準(zhǔn)備工作完畢后，現(xiàn)在要用了,調(diào)用智能安裝的代碼如下：

<code class="hljs cs"> //智能安裝
 private void smartInstall() {
 Uri uri = Uri.fromFile(new File("/mnt/sdcard/test.apk"));
 Intent localIntent = new Intent(Intent.ACTION_VIEW);
 localIntent.setDataAndType(uri, "application/vnd.android.package-archive");
 startActivity(localIntent);
 }</code>

(5) 手動(dòng)配置智能安裝服務(wù)

代碼運(yùn)行之后，還要用戶(hù)選擇開(kāi)啟智能安裝服務(wù)，讓用戶(hù)自己去找是不明智的，因此，我們要主動(dòng)跳到配置界面，代碼如下：

<code class="hljs cs">//跳轉(zhuǎn)到開(kāi)啟智能安裝服務(wù)的界面
Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
startActivity(intent);</code>

配置如下圖:

看到了嗎，上面顯示的就是Service里面的label的值，如果你沒(méi)有上面的選項(xiàng)，請(qǐng)檢查AndroidManifest里面Service的配置.
點(diǎn)擊'智能安裝App',開(kāi)啟服務(wù)，如下圖：

其中的提示文字就是我們?cè)趓es/xml/accessibility_service_config.xml文件中配置的description屬性

7 只能我們寫(xiě)的app可以自動(dòng)安裝

這樣寫(xiě)完代碼可以運(yùn)行，點(diǎn)擊按鈕自動(dòng)安裝sdcard上的test.apk.但是你會(huì)發(fā)現(xiàn)，所有apk都會(huì)自動(dòng)安裝，這就不符合我們的要求了，我們要求只能通過(guò)我們寫(xiě)的app來(lái)自動(dòng)安裝，其他apk還是要用戶(hù)手動(dòng)去點(diǎn)。怎么解決這個(gè)問(wèn)題呢？

思路是：在MainActivity中創(chuàng)建一個(gè)public static boolean flag,在MyAccessibilityService的onAccessibilityEvent()中加一個(gè)flag判斷，然后調(diào)用智能安裝前flag設(shè)為true,創(chuàng)建apk安裝事件的廣播接收器，當(dāng)apk安裝完成后，設(shè)置falg為false，這樣其他apk就不能自動(dòng)安裝了，就解決了這個(gè)問(wèn)題

下面上完整代碼.

服務(wù)配置文件

res/xml/accessibility_service_config.xml

<code class="hljs xml" data-filtered="filtered"></accessibility-service></code>

智能安裝服務(wù)

app/MyAccessibilityService.java:

<code class="hljs java">public class MyAccessibilityService extends AccessibilityService {
 private static final String TAG = "[TAG]";
 private Map<integer, boolean=""> handleMap = new HashMap<>();
 @Override
 public void onAccessibilityEvent(AccessibilityEvent event) {
 AccessibilityNodeInfo nodeInfo = event.getSource();
 if (nodeInfo != null && MainActivity.flag) {
  int eventType = event.getEventType();
  if (eventType == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED || eventType == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
  if (handleMap.get(event.getWindowId()) == null) {
   boolean handled = iterateNodesAndHandle(nodeInfo);
   if (handled) {
   handleMap.put(event.getWindowId(), true);
   }
  }
  }
 }
 }
 @Override
 public void onInterrupt() {
 }
 //遍歷節(jié)點(diǎn)，模擬點(diǎn)擊安裝按鈕
 private boolean iterateNodesAndHandle(AccessibilityNodeInfo nodeInfo) {
 if (nodeInfo != null) {
  int childCount = nodeInfo.getChildCount();
  if ("android.widget.Button".equals(nodeInfo.getClassName())) {
  String nodeCotent = nodeInfo.getText().toString();

  for (int i = 0; i < childCount; i++) {
  AccessibilityNodeInfo childNodeInfo = nodeInfo.getChild(i);
  if (iterateNodesAndHandle(childNodeInfo)) {
   return true;
  }
  }
 }
 return false;
 }
}</integer,></code>

最后是配置文件AndroidManifest.xml:

<code class="hljs xml"><manifest package="com.slientinstalltest" xmlns:android="https://schemas.android.com/apk/res/android">
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE">
  <intent-filter>
  <category android:name="android.intent.category.LAUNCHER">

 </activity>
 <service android:label="智能安裝App" android:name=".MyAccessibilityService" android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
  <intent-filter>
  </action></intent-filter>
  <meta-data android:name="android.accessibilityservice" android:resource="@xml/accessibility_service_config">
 </meta-data></service>
 </application>
</uses-permission></manifest></code>

注意：請(qǐng)把自己要安裝的apk放到sdcard上，并且修改代碼中的apk路徑和包名
