Usage

From source file:com.google.android.apps.muzei.provider.MuzeiProvider.java

private int updateSource(@NonNull final Uri uri, final ContentValues values, final String selection,
        final String[] selectionArgs) {
    Context context = getContext();
    if (context == null) {
        return 0;
    }//from   w  w  w . j  a  va 2s.  c  o  m

    // Only Muzei can set the IS_SELECTED field
    if (values.containsKey(MuzeiContract.Sources.COLUMN_NAME_IS_SELECTED)) {
        if (!context.getPackageName().equals(getCallingPackage())) {
            Log.w(TAG, "Only Muzei can set the " + MuzeiContract.Sources.COLUMN_NAME_IS_SELECTED
                    + " column. Ignoring the value in " + values);
            values.remove(MuzeiContract.Sources.COLUMN_NAME_IS_SELECTED);
        }
    }

    final SQLiteDatabase db = databaseHelper.getWritableDatabase();
    String finalWhere = selection;
    String[] finalSelectionArgs = selectionArgs;
    if (MuzeiProvider.uriMatcher.match(uri) == SOURCE_ID) {
        // If the incoming URI matches a single source ID, does the update based on the incoming data, but
        // modifies the where clause to restrict it to the particular source ID.
        finalWhere = DatabaseUtils.concatenateWhere(finalWhere,
                BaseColumns._ID + " = " + uri.getLastPathSegment());
    }
    String callingPackageName = getCallingPackage();
    if (!context.getPackageName().equals(callingPackageName)) {
        // Only allow other apps to update their own source

                MuzeiContract.Sources.COLUMN_NAME_COMPONENT_NAME + " LIKE ?");
        finalSelectionArgs = DatabaseUtils.appendSelectionArgs(finalSelectionArgs,
                new String[] { callingPackageName + "/%" });
    }
    int count = db.update(MuzeiContract.Sources.TABLE_NAME, values, finalWhere, finalSelectionArgs);
    if (count > 0) {
        notifyChange(uri);
    } else if (values.containsKey(MuzeiContract.Sources.COLUMN_NAME_COMPONENT_NAME)) {
        insertSource(MuzeiContract.Sources.CONTENT_URI, values);
