问题描述
我正在制作一个审计应用程序，必须从单选按钮和14个检查点的图像中收集是/否。
该应用程序在装有Android 10设备的设备上运行正常，但是在以某种随机方式收集4-6张图像并在相应的Imageview上显示它们并在String中收集Byte []后，在某些设备上（如在某些牛轧糖设备上）进行测试变量，应用程序也不会在日志中崩溃（现在通过调试器找到它，请参见下文）。看一下相机的代码。恢复活动后，单击照片后该应用程序崩溃了。
public void ClickImageFromCamera(String code) {
Intent CamIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File destination = new File(Environment.getExternalStorageDirectory(),System.currentTimeMillis() + ".jpg");
String img_Decodable_Str = String.valueOf(destination);
Log.e("img fromCam",String.valueOf(destination));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(getActivity(),getActivity().getApplicationContext().getPackageName() + ".provider",destination);
CamIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,uri);
} else {
uri = Uri.fromFile(destination);
CamIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,uri);
}
CamIntent.putExtra("return-data",true);
startActivityForResult(CamIntent,Integer.parseInt(code));
}

解决方法
好，我解决了。
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap,512,nh,true);
scaled.compress(Bitmap.CompressFormat.JPEG,80,byteArrayOutputStream);
byte[] imageBytes = byteArrayOutputStream.toByteArray();
Log.e("Original dimensions",bitmap.getWidth() + " " + bitmap.getHeight());
Log.e("Compressed dimensions",scaled.getWidth() + " " + scaled.getHeight());
Log.e("bytes",String.valueOf(bytes));
bitmap =null;
if(code ==50) {
imageCode1 = Base64.encodeToString(imageBytes,Base64.NO_WRAP);
Log.e("image1",imageCode1);
set_img_fascia.setImageBitmap(scaled);
}
if(code ==51) {
imageCode2 = Base64.encodeToString(imageBytes,imageCode2);
set_img_lollypop.setImageBitmap(scaled);
...So on
