安全异常请求PARTIAL_WAKE_LOCK

Question

I wrote a library which starts a STICKY Service when the main application calls a specific method. This Service acquires a PowerManager.PARTIAL_WAKE_LOCK during the execution of the onStartCommand() method:

PowerManager powerManager = (PowerManager)getSystemService(POWER_SERVICE);
if(powerManager != null) {
    wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, this.getClass().getName());
    wakeLock.acquire();
}

and the main application requires the WAKE_LOCK permission in its AndroidManifest.xml :

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="it.mcampana.myapp">

<application
    ....>

    <activity android:name=".SplashScreen" android:theme="@style/AppTheme.NoActionBar">
    <intent-filter>
            <action android:name="android.intent.action.MAIN" /
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

some activities...


</application>

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

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

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

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />

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

<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_SMS" />

<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />

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

<uses-permission
    android:name="android.permission.PACKAGE_USAGE_STATS"
    tools:ignore="ProtectedPermissions" />

</manifest>

(yes, there are a lot of permissions....but I need them!).

However, with some devices (eg, samsung SM-G950F, or ASUS_Z017D) I receive from ACRA the following exception

java.lang.SecurityException: Neither user 10182 nor current process has android.permission.WAKE_LOCK.

at the exact point where the Service requires the PARTIAL_WAKE_LOCK . The strange thing is that with other devices (eg, Xiaomi Mi 5, or Nexus 5) everything works fine.

**UPDATE: ** I found that this and other problems related to "missing permissions" (also with missing ACCESS_COARSE_LOCATION and READ_CALENDAR) mainly come from Samsung devices. As far as you know, there are some restrictions or additional security policies on Samsung devices?

Answer 1

In which API version are you testing? In API 26 and newer you should ask user for permissions during the runtime

ActivityCompat.requestPermissions(getContext(), new String[]{Manifest.permission.WAKE_LOCK},1);

then override onRequestPermissionsResult method to get the user response.
