private void loadWallpaper(boolean needsDraw, boolean needsReset)
上方法的异步改为同步进行测试(目的是将异步改为同步
private void loadWallpaper(boolean needsDraw, boolean needsReset) { mNeedsDrawAfterLoadingWallpaper |= needsDraw; if (mLoader != null) { if (needsReset) { mLoader.cancel(false /* interrupt */); mLoader = null; } else { if (DEBUG) { Log.d(TAG, "Skipping loadWallpaper, already in flight "); } return; } } /* SUN:jicong.wang remove for ALPS03943376 mLoader = new AsyncTask() { @Override protected Bitmap doInBackground(Void... params) { Throwable exception; try { if (needsReset) { mWallpaperManager.forgetLoadedWallpaper(); } return mWallpaperManager.getBitmap(); } catch (RuntimeException | OutOfMemoryError e) { exception = e; } if (isCancelled()) { return null; } if (exception != null) { // Note that if we do fail at this, and the default wallpaper can't // be loaded, we will go into a cycle.
