使用try-catch,createBitmap无法捕获Java(Android)异常

标签: android exception android-bitmap

我有一部分代码,我使用此代码四次,但第六次,我的应用程序崩溃,我没有得到任何异常或错误代码。代码是:

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();
    }

但是没有发生。我在不同的决定中测试我的应用程序,在Sony Xperia Z3,Moto G,GenyMotion中使用不同的模拟器工作正常。

但是我的摩托罗拉Moto Max不适用。

日志控制台不显示错误,但打印一些代码:

有什么建议吗?

答案 0 :(得分:0)

我很确定你的设备内存不足,这就是为什么第6个createBitmap会使你的应用程序崩溃的原因。请尝试以下方法:

try{
    Bitmap resizedBitmap = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, false);
} catch (Exception e) {
    e.printStackTrace();
} catch (OutOfMemoryError e) {
    e.printStackTrace();
}

这应该正确地为抛出的错误提供输出。让我知道输出,你可能需要手动调用System.gc()来处理你自己的所有垃圾收集。
