Android Question About runtime permission

[marcick]

Just a confirmation if I'm doing correctly:
I have declared in "configure paths" the android-23 platform. This because I want to manage a runtime permission in Android 6 and force the user to exclude the App from the battery optimization

Sub Activity_Resume
If GetAndroidApiLevel>=23 Then
        Dim JavaObject1 As JavaObject
        JavaObject1.InitializeContext
        Dim Ignoring As Boolean=JavaObject1.RunMethod("isIgnoringBatteryOptimizations", Null)
        If Ignoring=False Then
            Msgbox("it is mandatory to answer YES to the following box to exclude this App from battery optimization.", "Battery optimization")
            RuntimePermissions1.CheckAndRequest("android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS")
        End If
    End If

I thought first that I had also to declare in the manifest the android:targetSdkVersion="23"
And then I discovered I had to manage in runtime all the other dangerous permission, like write to external storage.

The question is: can I have the android-23 platform in "configure paths" and specify android:targetSdkVersion="22" (not 23) in the manifest ?
This way I can use just the runtimepermission I need, without need to modify much other code.
It seems to work, just need confirmation.

You are confusing different things. Runtime permissions are only relevant if targetSdkVersion is set to 23+. The android version under Tools - Configure Paths is not important in this case.

The code you posted if not related to the runtime permissions feature.

The answer is that you can set the targetSdkVersion to 22.

I got help for that code (I didn't write it) and there is another part in Java to shows a dialog that enables the user to approve whitelisting the app.
But to understand: why you say it is not related to the runtime permission feature ?

 

[Erel]

Why can't you add this permission with AddPermission?

Are there any other "dangerous" permissions that your app depends on (check it under Logs - List Permissions and look for the wildcard mark)?

 

[marcick]

Yes, I have the AddPermission in the manifest

AddPermission(android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)

but this does not mean my app is whitelisted ...
With the manifest entry and thencode posted before and some other Java stuff, my app can programmatically request the user to whitelist the app and exclude it from the battery optimization.
I think my code is related to the runtime permissions feature, right ?

there are a lot of other dangerous permissions and if I switch to target 23 I need to modify much code to manage them. Would avoid now ....

 

[Erel]

Does it work when targetSdkVersion is set to 22?

 

[marcick]

Yes, it works. But I wonder if it is correct ....

 

[Erel]

It is correct but not required. You don't need to use runtime permissions here.

 

[marcick]

Ahhh.... understand now.
I have removed

RuntimePermissions1.CheckAndRequest("android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS")

And just use the java code to open the dialog and ask the user to whitelist the app.
It works fine.
Thank you very much, as usual.

Hi

can you share you code to do this please

J.

 

[marcick]

Yes:

Sub Activity_Resume
    If GetAndroidApiLevel>=23 Then
        Dim JavaObject1 As JavaObject
        JavaObject1.InitializeContext
        Dim Ignoring As Boolean=JavaObject1.RunMethod("isIgnoringBatteryOptimizations", Null)
        If Ignoring=False Then
            Msgbox("Pleas confirm the following to exclude this app from battery optimization.", "Battery Optimization")
            'RuntimePermissions1.CheckAndRequest("android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS")
            Dim JavaObject1 As JavaObject
            JavaObject1.InitializeContext
            JavaObject1.RunMethod("ShowPermissionDialog", Null)
        End If
    End If
End Sub

Thanks for sharing,

I get the following:

Using a HTC M9 Android 6.0, <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="23"/>

Any Ideas ?

Sorry, add this code :

#If JAVA
import android.content.Context;
import android.content.Intent;
import android.os.PowerManager;
import android.provider.Settings;
import android.net.Uri;
import anywheresoftware.b4a.BA;

public boolean isIgnoringBatteryOptimizations(){
Context context=this;
String packageName = context.getPackageName();
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
return pm.isIgnoringBatteryOptimizations(packageName);
}

public void ShowPermissionDialog(){
    Intent intent = new Intent();
    Context context=this;
    String packageName = context.getPackageName();
    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    if (pm.isIgnoringBatteryOptimizations(packageName)){
        BA.LogInfo("isIgnoringBatteryOptimizations TRUE");
        intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);
    } else {
        BA.LogInfo("isIgnoringBatteryOptimizations FALSE");
        intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
        intent.setData(Uri.parse("package:" + packageName));
    }
    context.startActivity(intent);
}
#End If

thanks for that, seems to be going around in a loop, with the message box poping up, and the following logged:

isIgnoringBatteryOptimizations FALSE

[marcick]

uhm. That's the code I'm using and works fine but sometimes it's hard to collect all the parts needed ......
Looking to the manifest, I see I have added this also, hope it's the last missing part ....

' add new permission to ignore doze_mode in Android 6
AddPermission(android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)

 

[Jmu5667]

That's the One !

Thank for the help

Good
