BroadcastReceiver Intent.ACTION

本文介绍了BroadcastReceiver Intent.ACTION_PACKAGE_ADDED/REMOVED Android Oreo的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这是我的广播接收器类，主要是其实现.

This is my broadcast receiver class and the implementation of it in main.

问题在于onReceive方法永远不会被调用.

Problem is that onReceive method never gets called.

class MyBroadcastReceiver : BroadcastReceiver() { override fun onReceive(p0: Context?, p1: Intent?) { Toast.makeText(p0, "It works", Toast.LENGTH_LONG).show() } } class MainActivity : AppCompatActivity() { ...... private var broadcastReceiver: MyBroadcastReceiver = MyBroadcastReceiver() override fun onCreate(savedInstanceState: Bundle?) { ...... registerReceiver(broadcastReceiver, IntentFilter().apply { addAction(Intent.ACTION_PACKAGE_ADDED) addAction(Intent.ACTION_PACKAGE_REMOVED) }) } override fun onDestroy() { super.onDestroy() unregisterReceiver(broadcastReceiver) } }

请帮助.预先感谢.

推荐答案

通常BroadcastReceiver需要设置许多步骤.

Usually the BroadcastReceiver needs a number of steps to be set up.

首先您没有将清单传递给清单吗?

First of all did yout pass to the manifest the receiver?

<receiver android:name=".MyBroadcastReceiver" android:exported="true"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED"/> <action android:name="android.intent.action.INPUT_METHOD_CHANGED" /> </intent-filter> </receiver>

编辑 :请参阅此帖子，建议在ACTION_PACKAGE_FULLY_REMOVED或JobScheduler

Edit: Please see this post, where is suggested ACTION_PACKAGE_FULLY_REMOVED or JobScheduler

还尝试在模拟器上重新安装应用程序

try also to reinstall the app on the emulator
