Getting java.lang.SecurityException: Permission Denial while setting wallpaper in Android

Question

I have an application of wallpapers where I allow the user to set wallpaper directly from the app. Here I convert http url of image into Bitmap and call WallpaperManager class of Android.

Following is code for converting URL to bitmap and setting into WallpaperManager bitmap:

private void setWallpaper() {
        WallpaperManager wallpaperManager = WallpaperManager.getInstance(this);
        try {
            Bitmap image = getBitMapFromHttpURL();
            if (image != null) {
                wallpaperManager.setBitmap(getBitMapFromHttpURL());
                image.recycle();
                image = null;
            } else {
                Toast.makeText(this, "Failed to set wallpaper",
                        Toast.LENGTH_LONG).show();
            }
        } catch (IOException e) {

        } catch (Exception es) {

        }
    }

It fails on this line wallpaperManager.setBitmap(getBitMapFromHttpURL()); with the following exception:

java.lang.SecurityException: Permission Denial: writing com.android.providers.settings.SettingsProvider uri content://settings/system from pid=21407, uid=10133 requires android.permission.WRITE_SETTINGS, or grantUriPermission()

The exception you are getting clearly defines you need to add the permission in Manifest.

java.lang.SecurityException: Permission Denial: writing com.android.providers.settings.SettingsProvider uri content://settings/system from pid=21407, uid=10133 requires android.permission.WRITE_SETTINGS, or grantUriPermission()

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

The logcat is clear:

java.lang.SecurityException: Permission Denial: writing com.android.providers.settings.SettingsProvider uri content://settings/system from pid=21407, uid=10133 requires android.permission.WRITE_SETTINGS, or grantUriPermission()

So you just need to add this permission in your Manifest file:

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

under application tag.

Hope it helps.

Its very difficult to find device i mentioned to test. I will add permission and release it with next update – virendrao Nov 12 '14 at 04:33
thanks but it will be user specific may be i should catch exception and let user know you dont have rights ? – virendrao Nov 12 '14 at 04:39
@vo12 Yes. may be using try catch around that line. And see [this](http://stackoverflow.com/a/9153850/1777090) for more. – MysticMagicϡ Nov 12 '14 at 04:44

Your are missing to add WRITE_SETTINGS permission in AndroidManifest.xml.

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

If you dont required Bitmap object longer then directly check from bitamp using getBitMapFromHttpURL instead declare Bitamp object.

if (getBitMapFromHttpURL() != null) {
    wallpaperManager.setBitmap(getBitMapFromHttpURL());
} else {
    Toast.makeText(this, "Failed to set wallpaper",Toast.LENGTH_LONG).show();
}

May you forgot to take any of this Permissions:

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.SET_WALLPAPER" />
<uses-permission android:name="android.permission.SET_WALLPAPER_HINTS" />
