Question

我有一个启动完整的广播接收器，但它没有按预期工作。全屏活动也不需要STATUS_BAR权限。

我试图在手机启动时查看LogCat日志，这就是我发现的：

LOG

 04-11 14:23:48.718: W/PackageManager(133): Not granting permission 
    android.permission.BIND_DEVICE_ADMIN to package com.myprojects.myapp (protectionLevel=2 flags=0xbe46)

有什么理由会发生这种情况？

我的清单文件有：

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

<receiver android:name="com.myprojects.myapp.DeviceAdministrationReceiver"
        android:permission="android.permission.BIND_DEVICE_ADMIN">  
       <meta-data android:name="android.app.device_admin" android:resource="@xml/device_admin_policies" />

    <intent-filter>
            <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" />
    </intent-filter>
</receiver>

<receiver android:name="com.myprojects.myapp.BootCompleteReceiver">  
        <intent-filter>  
            <action android:name="android.intent.action.BOOT_COMPLETED" />  
        </intent-filter>  
</receiver>

修改和其他两个类似的日志：

04-11 14:24:17.810: W/PackageManager(133): Not granting permission android.permission.STATUS_BAR to package com.myprojects.myapp (protectionLevel=3 flags=0xbe46)

04-11 14:24:17.810: W/PackageManager(133): Not granting permission android.permission.WRITE_SECURE_SETTINGS to package com.myprojects.myapp (protectionLevel=3 flags=0xbe46)

如果您是扩展DeviceAdminReceiver，那么必须为接收器添加元数据和 description ，如下所示：

<receiver 
    android:name=".AdminReceiver" 
    android:description="@string/description" 
    android:label="@string/labelValue" 
    android:permission="android.permission.BIND_DEVICE_ADMIN" 
 > 
 <meta-data  
  android:name="android.app.device_admin" 
  android:resource="@xml/lockourscreen"/> 
  <intent-filter> 
   <action android:name="android.app.action.DEVICE_ADMIN_ENABLED" /> 
  </intent-filter> 
</receiver>

{p} BIND_DEVICE_ADMIN doc说： Must be required by device administration receiver, to ensure that only the system can interact with it.

所以从应用程序级别删除<uses-permission android:name="android.permission.BIND_DEVICE_ADMIN"/>行

Logcat：不授予android.permission.BIND_DEVICE_ADMIN权限以包com.myprojects.myapp（protectionLevel = 2 flags = 0xbe46）
