Android动态广播添加权限

第一步：自己定义权限，并且使用自定义权限

<uses-permission android:name="com.cn.customview.permissions.MY_BROADCAST" />

<permission
    android:name="com.cn.customview.permissions.MY_BROADCAST"
    android:protectionLevel="signature" >
</permission>

给这个应用程序定义了一个permissions并且uses-permission申明使用，这是这个应用就有了这个权限，并且应用内部的注册的动态广播也拥有了这个权限。

第二步：定义注册广播
private static final String BROADCAST_PERMISSION_DISC = “com.cn.customview.permissions.MY_BROADCAST”;
private static final String BROADCAST_ACTION_DISC = “com.cn.customview.permissions.my_broadcast”;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.broadcast_permissions_activity);
    ButterKnife.bind(this);
    // 注册广播接收
    BroadcastReceiver receiveBroadCast = new ReceiveBroadCast();
    IntentFilter filter = new IntentFilter();
    filter.addAction(BROADCAST_ACTION_DISC); // 只有持有相同的action的接受者才能接收此广播
    registerReceiver(receiveBroadCast, filter,BROADCAST_PERMISSION_DISC,null);
}

public class ReceiveBroadCast extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(BroadcastPermissionsActivity.this,
                "receive broadcast", 0).show();
    }

}

注册一个广播，并且申明，这个广播需要BROADCAST_PERMISSION_DISC权限才能收到消息。但是我们应用程序已经注册了这个权限。所以是有这个权限的。

第三步： 发送广播

@OnClick(R.id.btn_send_broadcast)
public void sendBroadcastWithPermissions() {
    Intent intent = new Intent();  //Itent就是我们要发送的内容
    intent.putExtra("data", "this is data from broadcast "+Calendar.getInstance().get(Calendar.SECOND));  
    intent.setAction(BROADCAST_ACTION_DISC);   //设置你这个广播的action，只有和这个action一样的接受者才能接受者才能接收广播
    sendBroadcast(intent,BROADCAST_PERMISSION_DISC);   //发送广播
}
