Android 8.1静态广播的使用以及添加权限

在Android 8.1后我使用静态广播时会发现接收不到广播，下面有两种方法：
1、动态广播替换静态广播
2、保留原来的静态广播，使用setComponent参数

 Intent intent = new Intent();
        intent.setAction("com.wq.package.silentinstaller");
        intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);
        intent.setComponent(new ComponentName("com.android.packageinstaller",
                "com.android.packageinstaller.MyReceiver"));
       sendBroadcast(intent);

为了发送广播的时候只让特定的某一个应用程序APP接收到数据，而不想其他应用程序接收到数据的时候，需要配置权限。
一、广播接收者设置权限：
在AndroidManifest.xml中添加权限和定义静态广播

创建一个静态广播MyReceiver.java类

public class MyReceiver extends BroadcastReceiver {
	private static final String TAG = "SilentInstallReceiver";
	private Context mContext;
	private static final String ACTION_SILENCE_INSTALL = "com.wq.package.silentinstaller";
	private static final String KEY_FILE_PATH = "file_path";
	private static final String KEY_PACKAGE_NAME = "package_name";
	private static final int MSG_SILENT_INSTALL = 1;
	private Handler mHandler = new Handler() {
		public void handleMessage(android.os.Message msg) {
			switch (msg.what) {
			case MSG_SILENT_INSTALL:
				Intent intent = (Intent) msg.obj;
				String filePath = intent.getStringExtra(KEY_FILE_PATH);
				String packageName = intent.getStringExtra(KEY_PACKAGE_NAME);
				Log.i(TAG, "---MSG_SILENT_INSTALL filePath=" + filePath + ",packageName=" + packageName);
				SilentInstallManager.getInstance(mContext).startInstall(filePath);
				break;

			default:
				break;
			}
		};
	};

	@Override
	public void onReceive(Context context, Intent intent) {
		String action = intent.getAction();
		Log.i(TAG, "onReceive() action="+action);
		if (ACTION_SILENCE_INSTALL.equals(action)) {
			mContext = context;
			Message msg = Message.obtain(mHandler);
			msg.what = MSG_SILENT_INSTALL;
			msg.obj = intent;
			mHandler.sendMessage(msg);
		}

	}
	
	/**
	 * installPackageName  : The package name of apk you want to install.
	 * apkFilePath         : The path of the apk file.
	 * 
	 private void install(String installPackageName, String apkFilePath){
		Intent intent = new Intent();
		intent.setAction("com.wq.package.silentinstaller");
		intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);
		intent.setComponent(new ComponentName("com.android.packageinstaller",
				"com.android.packageinstaller.MyReceiver"));
		intent.putExtra("package_name", installPackageName);
		intent.putExtra("file_path", apkFilePath);
		mContext.sendBroadcast(intent);
	}
	*/
}

二、广播发送者
发送广播的应用装备该权限

添加一个按钮发送广播

 Intent intent = new Intent();
 intent.setAction("com.wq.package.silentinstaller");
intent.addFlags(Intent.FLAG_RECEIVER_FOREGROUND);
intent.setComponent(new ComponentName("com.android.packageinstaller",
                "com.android.packageinstaller.MyReceiver"));
 sendBroadcast(intent);
