监听apk的安装和卸载代码

1、创建广播类，继承BroadcastReceiver

public class PackageBroadCastReceiver extends BroadcastReceiver {    private static final int PACKAGE_NAME_START_INDEX = 8;     @Override   public void onReceive(Context context, Intent intent) {    if (intent == null) {     return;    }    if (intent.getAction().equals(Intent.ACTION_PACKAGE_ADDED)) {    String data = intent.getDataString();      if (data == null || data.length() <= PACKAGE_NAME_START_INDEX) {     return;   }    String packageName = data.substring(PACKAGE_NAME_START_INDEX);   }    }  }

2、在manifest文件中添加声明

<receiver android:name=".PackageBroadCastReceiver">             <intent-filter>                <action android:name="android.intent.action.PACKAGE_ADDED" />                <action android:name="android.intent.action.PACKAGE_REMOVED" />                <data android:scheme="package" />                </intent-filter>  </receiver>
