java - 处理 Picasso(重新)抛出的异常

Question

是否可以捕获这样的异常？我可以使用 Thread.UncaughtExceptionHandler 吗？

java.lang.IllegalArgumentException: RemoteViews for widget update exceeds maximum bitmap memory usage (used: 1000000, max: 921600) The total memory cannot exceed that required to fill the device's screen once.

我看到 Picasso 使用 Handler 抛出异常:

Picasso.HANDLER.post(new Runnable() { ...

是否可以从我的代码中捕获此异常？

Answer 1

在开发者网站中:

The total Bitmap memory used by the RemoteViews object cannot exceed that required to fill the screen 1.5 times, ie. (screen width x screen height x 4 x 1.5) bytes.

在您的特定情况下，当从流加载的位图大于可能的大小时，就会发生错误。

您需要在比较后解码图像以获得适合您的布局的尺寸!

或通过 picasso 库上的.resize(imageWidth, imageHight)!

希望这有帮助:) ..
