遇到难题求高手帮忙解决--Android P开始监听不到关机广播
背景:
最近在做一个关于android的续航时间测试apk,从开始测试记录时间到低电自动关机时这整个的时间,当前采用监听关机广播的来实际统计续航时间,但遇到的问题是同样的测试apk在android8及以下系统均能正常监听到关机广播,但从android 9开始就监听不到关机广播了。
下面是我的监听广播注册方法(采用静态注册关机 广播方式)
AndroidManifest.xml如下
1 <?xml version="1.0" encoding="utf-8"?> 2 <manifest xmlns:android="http://schemas.android.com/apk/res/android" 3 package="com.dou.dou"> 4 5 <application 6 android:allowBackup="true" 7 android:icon="@mipmap/ic_launcher" 8 android:label="@string/app_name" 9 android:roundIcon="@mipmap/ic_launcher_round" 10 android:supportsRtl="true" 11 android:theme="@style/AppTheme"> 12 13 <receiver 14 android:name=".ShutDownBroadcastReceiver" 15 android:exported="true"> 16 <!--<intent-filter>--> 17 <!--<action android:name="android.intent.action.BOOT_COMPLETED" />--> 18 <!--<category android:name="android.intent.category.HOME" />--> 19 <!--</intent-filter>--> 20 21 <intent-filter> 22 <action android:name="android.intent.action.ACTION_SHUTDOWN" /> 23 <!--<category android:name="android.intent.category.HOME" />--> 24 </intent-filter> 25 </receiver> 26 </application> 27 28 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 29 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 30 <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 31 <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/> 32 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 33 <uses-permission android:name="android.permission.READ_PHONE_STATE"/> 34 35 </manifest>
下面是实现接收关机广播的处理实现
1 import android.content.BroadcastReceiver; 2 import android.content.Context; 3 import android.content.Intent; 4 5 import java.io.File; 6 import java.io.FileWriter; 7 import java.io.IOException; 8 import java.text.SimpleDateFormat; 9 import java.util.Date; 10 11 public class ShutDownBroadcastReceiver extends BroadcastReceiver { 12 @Override 13 public void onReceive(Context context, Intent intent){ 14 System.out.println("---------Shut down-------------"); 15 File file = new File ("/sdcard/result.txt"); 16 try { 17 if(!file.exists()) 18 { 19 file.createNewFile(); 20 } 21 FileWriter writer = null; 22 23 writer = new FileWriter(file, true); 24 25 writer.write("Shut_down [" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format((new Date()).getTime()) + "]\n"); 26 writer.close(); 27 } catch (IOException e) { 28 e.printStackTrace(); 29 } 30 } 31 }
