在我的应用程序中,我从相机获取图像。这段代码完全适用于大多数设备,但是当我在sumsung galaxy grand quattro应用程序中进行测试时崩溃了。

这是我的尝试:

if(resultCode == RESULT_OK) {
    Bitmap photo = (Bitmap)data.getExtras().get("data");
    try {

        resized = Bitmap.createScaledBitmap(photo, 200, 200, true);
        final_image = Bitmap.createScaledBitmap(photo, 200, 200, true);
    } catch(Exception e) {
        Toast.makeText(getApplicationContext(), "Failed To Load ", 5000).show();
    }

    int currentapiVersion = android.os.Build.VERSION.SDK_INT;
    if(currentapiVersion >= android.os.Build.VERSION_CODES.KITKAT) {

        Bitmap blurredBitmap = BlurBuilder.blur(getApplicationContext(), resized);
        BitmapDrawable ob = new BitmapDrawable(getResources(), blurredBitmap);
        ll.setBackground(ob);

    } else {
        Bitmap blur = BitmapFactory.decodeResource(getResources(), R.drawable.blurback);
        BitmapDrawable ob = new BitmapDrawable(getResources(), blur);
        ll.setBackground(ob);
    }
    try {
        Bitmap circleimg = getCircularBitmapWithWhiteBorder(resized, 2);
        iv.setImageBitmap(circleimg);
        final_image.compress(Bitmap.CompressFormat.JPEG, 100, baos);
        byte[] b = baos.toByteArray();
        String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);
        imgpath = encodedImageString;
    } catch(Exception e) {
    }
}

注意:

I tasted my app in
  1. Micromax Canvas Knight - kitkat
  2. Sony Xperia c3 - 棒棒糖
  3. Micromax Canvas 2- jellybean
  4. 完成工作中的设备

    1. 三星galaxy grand quattro - jellybean(应用程序崩溃)
    2. LogCat:

2 个答案:

答案 0 :(得分:2)

崩溃的原因是数据为空。这在某些设备上发生,而是使用内容提供商。数据将包含您可以读出的路径:

Bitmap photo;
if(data.getData() == null) {
    photo = (Bitmap)data.getExtras().get("data");
} else {
    photo = MediaStore.Images.Media.getBitmap(getContentResolver(), data.getData());
}

那应该适合你。

这不是解决方案,但可以帮助隔离问题。

打开原生相机应用程序,选择较低分辨率,2Mpx,例如,现在,打开您的应用程序并进行测试。

我使用Cordova,当本机相机应用程序具有最高分辨率时,我意识到应用程序崩溃。

在尝试调整图像大小的那一刻可能是一个内存问题,因为它需要在内存中打开,或者需要在主存储中有一个大的缓存空间,并且没有空间可用。
