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 <receiver14 android:name=".ShutDownBroadcastReceiver"15 android:exported="true">16 -->17 "android.intent.action.BOOT_COMPLETED" />-->18 "android.intent.category.HOME" />-->19 -->20 21 22 <action android:name="android.intent.action.ACTION_SHUTDOWN" />23 "android.intent.category.HOME" />-->24 25 26 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
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 @Override13 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 }
