本文介绍了使用try-catch，createBitmap无法捕获Java（Android）异常的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一部分代码，我四次使用此代码，但是第六次，我的应用程序崩溃了，我没有任何异常或错误代码。代码是：
I have a part of code, i use this code four times, but the the sixth time, my application crash , i don't get any Exception or error code. The code is:
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
我尝试使用：
try{
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
}catch (Exception e){
e.printStackTrace();
e.getMessage();
}catch (OutOfMemoryError o){
o.printStackTrace();
o.getMessage();
}catch (AssertionError a){
a.printStackTrace();
a.getMessage();
} catch ( Throwable t ){
t.printStackTrace();
t.getMessage();
}
但是什么也没发生。我在不同的存储库中测试了我的应用程序，在带有不同模拟器的Sony Xperia Z3，Moto G和GenyMotion上运行良好。
But nothings happen. I test my application in diferent dispositives, works fine in a Sony Xperia Z3, Moto G , GenyMotion with different simulators.
但是在我的Motorola Moto Max中不起作用。
But dont works in my Motorola Moto Max.
日志控制台未显示错误，但会打印一些代码：
The log console dont shows an error, but print some codes:

有什么建议吗？
推荐答案
我很确定您的设备内存不足，这就是第6个createBitmap会使您的设备崩溃的原因应用。请尝试以下操作：
I am pretty sure you are running out of memory for your device, which is why the 6th createBitmap is going to crash your application. Try the following:
try{
Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
} catch (Exception e) {
e.printStackTrace();
} catch (OutOfMemoryError e) {
e.printStackTrace();
}
这应该正确地输出抛出的错误。让我知道输出，您可能需要手动调用System.gc（）来处理您自己的所有垃圾收集。
This should properly give output for errors that are thrown. Let me know the output, you might need to manually call System.gc() to handle all the garbage collection youself.
