原因：android.content.ActivityNotFoundException:找不到可处理意图{act=android.media.action.IMAGE\u捕获的活动

/*捕获图像法*/

 private void captureImage() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//Start intent with Action_Image_Capture

            file = CameraUtils.getfile(Home.this);
            fileUri = CameraUtils.getOutputMediaFileUri(Home.this);//get fileUri from CameraUtils
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);//Send fileUri with intent
            startActivityForResult(intent, CAMERA_REQUEST_CODE);//start activity for result with CAMERA_REQUEST_CODE

    }


   @Override

错误

  Caused by: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.media.action.IMAGE_CAPTURE flg=0x3 clip={text/uri-list U:file:///storage/emulated/0/Android/data/com.camera_demo/files/Pictures/Camera/IMG_20180402_151052.jpg} (has extras) }

检查您是否获得了正确的文件URI。您应该获得如下URI：

if(Build.VERSION.SDK_INT > Build.VERSION_CODES.M){
    picUri = FileProvider.getUriForFile(activity, BuildConfig.APPLICATION_ID + ".provider", createImageFile());
}else{
    picUri = Uri.fromFile(createImageFile());
}

而

createImageFile（）

类似于：

public File createImageFile() {
        // Create an image file name
        Date date = new Date();
        String timeStamp = Const.dateFormat.format(date);
        timeStamp = timeStamp + "_" + Const.imgTimeFormat.format(date);
        String imageFileName = "IMG_" + timeStamp + ".jpg";
        File albumF = getAlbumDir();
        File imageF = new File(albumF, imageFileName);
        return imageF;
    }

你忘了问问题。可能是重复的
