API 27无法接收BOOT_COMPLETED操作 [英] BOOT_COMPLETED action cannot be received with API 27

问题描述

下面的代码虽然可以使用API​​ 25，但不能通过API 27收到 BOOT_COMPLETED 操作。

但是根据官方文档，该操作属于隐式广播示例。 p>

当我输入 am broadcast的adb命令-android.intent.action.BOOT_COMPLETED 时，以下消息显示在在控制台上：

 不允许后台执行：接收Intent {act = android.intent.action.BOOT_COMPLETED flg = 0x400010}到com .boottest / .OnBootReceiver 
  

是否有机会克服此问题？

我的 AndroidManifest.xml 文件：

  ... 
<使用权限android：name = android.permission.RECEIVE_BOOT_COMPLETED /> 
 
< uses-sdk android：minSdkVersion = 16 android：targetSdkVersion = 27 /> 
 
<应用程序...> 
 .... 
< receiver android：name =。OnBootReceiver android：exported = true> 
<意图过滤器> 
< action android：name = android.intent.action.BOOT_COMPLETED /> 
< / intent-filter> 
< / receiver> 
< / application> 
 .... 
  

我的 build.gradle 文件：

  ... 
 android {
 compileSdkVersion 27 
 buildToolsVersion  27.0.1 
 
 defaultConfig {
 applicationId com.boottest 
 minSdkVersion 16 
 targetSdkVersion 27 
 versionCode 1 
 versionName 1.0  
 ndk {
 abiFilters armeabi-v7a， x86 
} 
} 
 ... 
}

} 
 
 allprojects {

} 
} 
} 
  

我的 OnBootReceiver.java 文件：

 包com.boottest; 
 
 import android.content.BroadcastReceiver; 
 import android.content.Context; 
 import android.content.Intent; 
 import android.util.Log; 
 
公共类OnBootReceiver扩展了BroadcastReceiver {
 @Override 
 public void onReceive（Context context，Intent intent）{
 Log.d（ BootTest， OnBootReceiver-收到广播！）; 
} 
} 
  

解决方案

问题是Android模拟器。

它可以按预期工作，并且 OnBootReceiver 接收器类的评估结果为 BOOT_COMPLETED 使用Genymotion时启动时的操作。

The code below does not receive BOOT_COMPLETED action with API 27 although works with API 25.

However this action is among Implicit Broadcast Exeptions according to the official documentation.

When I enter the adb command of am broadcast -a android.intent.action.BOOT_COMPLETED the message below is shown on the console:

Background execution not allowed: receiving Intent { act=android.intent.action.BOOT_COMPLETED flg=0x400010 } to com.boottest/.OnBootReceiver

Is there any chance to overcome this issue?

My AndroidManifest.xml file:

...
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="27" />

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

My build.gradle file:

...
android {
    compileSdkVersion 27
    buildToolsVersion "27.0.1"

    defaultConfig {
        applicationId "com.boottest"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }
    ...
}

dependencies {
    compile fileTree(dir: "libs", include: ["*.jar"])
    compile "com.android.support:appcompat-v7:27.0.+"
    compile "com.facebook.react:react-native:+"  // From node_modules
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

My OnBootReceiver.java file:

package com.boottest;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class OnBootReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
        Log.d("BootTest", " OnBootReceiver - Received a broadcast!");
  }
}

解决方案

The problem was Android Emulator.

It works as expected and OnBootReceiver receiver class evaluates BOOT_COMPLETED action on startup when using Genymotion.
