分析:

assertTrue()方法本身会抛出一个error,但外层的调用者LocalPhotoSource并没有catch这个异常导致问题出现.

// Throws AssertionError if the input is false.
    public static void assertTrue(boolean cond) {
        if (!cond) {
            throw new AssertionError();
        }
    }

src/com/android/gallery3d/gadget/LocalPhotoSource.java

 private boolean isContentSound(int totalCount) {
        if ( mPhotos.size() < Math. min(totalCount, MAX_PHOTO_COUNT)) return false ;
        if ( mPhotos.size() == 0) return true ; // totalCount is also 0

        StringBuilder builder = new StringBuilder();
        for (Long imageId : mPhotos) {
            if (builder.length() > 0) builder.append( ",");
            builder.append(imageId);
        }
        Cursor cursor = mContext.getContentResolver().query(
                CONTENT_URI, COUNT_PROJECTION ,
                String. format("%s in (%s)", Media. _ID, builder.toString()),
                null, null);
        if (cursor == null) return false ;
        try {
            Utils. assertTrue(cursor.moveToNext());
            return cursor.getInt(0) == mPhotos .size();
        //Vinky.Q.Wang added start
        } catch(AssertionError assertionError){
             return false ;
        //Vinky.Q.Wang added end
        } finally {
            cursor.close();
        }
    }
