Getting java.lang.SecurityException: permission denial when setting wallpaper in Android
I have a wallpaper application where I allow the user to set the wallpaper directly from the application. Here I am converting the http url of the image to Bitmap and calling WallpaperManager
the Android class.
Below is the code to convert URL to bitmap and set to bitmap WallpaperManager
:
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) {
}
}
On this line, wallpaperManager.setBitmap(getBitMapFromHttpURL());
it fails on 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()

What could be the reason?

With an exception that you clearly define, you need to add permission to your manifest.
java.lang.SecurityException: Permission denied: entry 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 log code 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 to your manifest file:
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
in the app tag.
Hope it helps.

Missing to add WRITE_SETTINGS permission in AndroidManifest.xml.
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
If you don't need a Bitmap object for longer, then directly check with bitamp using getBitMapFromHttpURL, declare a Bitamp object instead.
if (getBitMapFromHttpURL() != null) {
wallpaperManager.setBitmap(getBitMapFromHttpURL());
} else {
Toast.makeText(this, "Failed to set wallpaper",Toast.LENGTH_LONG).show();
}
