Question

我有一个没有任何活动的应用程序，只是一个接收者。我重新启动接收器，然后使用adb安装apk。但是，我从未到达此接收器。为什么我永远都无法到达接收器（例如在重启时）？

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="amiin.bazouk.application.com.doproject">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <receiver android:name=".DeviceOwnerReceiver">
    </receiver>
</application>

</manifest>

DeviceOwnerReceiver.java：

package amiin.bazouk.application.com.doproject;


import android.app.Activity;
import android.app.admin.DeviceAdminReceiver;
import android.app.admin.DevicePolicyManager;
import android.content.BroadcastReceiver;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class DeviceOwnerReceiver extends DeviceAdminReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if(action.equals("android.intent.action.BOOT_COMPLETED")){
            System.out.println("ADRIEN");
        }

        if(action.equals("android.intent.action.BATTERY_CHANGED")){
            System.out.println("ADRIEN");
        }
    }

    @Override
    public void onProfileProvisioningComplete(Context context, Intent intent) {
        if (Util.isDeviceOwner(context)){
            //start enforcing policies: example if kioskModeEnabled->startKiostMode
        }
    }

    @Override
    public void onLockTaskModeEntering(Context context,Intent intent,String pkg) {
        if (Util.isDeviceOwner(context)){
            //start enforcing kiosk mode policies like this example when this property is done:
            DevicePolicyManager dpm = (DevicePolicyManager) context.getSystemService(Activity.DEVICE_POLICY_SERVICE);;
            dpm.setStatusBarDisabled(new ComponentName(context.getApplicationContext(), DeviceOwnerReceiver.class),false);
        }
    }

    @Override
    public void onLockTaskModeExiting(Context context,Intent intent) {
        //exit kioskmode
    }
}

Answer 1

我认为您需要设置RECEIVE_BOOT_COMPLETED权限，并为BOOT_COMPLETED，QUICKBOOT_POWERON之类的服务配置意图过滤器。

看看这个，他们的回答很好地解释了这个问题 https://stackoverflow.com/a/46294732/7774671

Answer 2

清单中的接收器中缺少一些东西。试试这个。

<receiver 
        android:name=".DeviceOwnerReceiver"
        android:enabled="true"
        android:exported="true">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<action android:name="android.intent.action.BATTERY_CHANGED"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</receiver>

Answer 3

如果广播接收器没有故意注册，则不会被调用。此关联接收者/意图可以使用意图过滤器在清单中声明。

<receiver android:name=".DeviceOwnerReceiver">
  <intent-filter>
   <action android:name="android.intent.action.BOOT_COMPLETED"></action>
<action android:name="android.intent.action.BATTERY_CHANGED"></action>
  </intent-filter>
</receiver>

未达到接收者
