当我在android 7.0中尝试打开相机时，应用程序崩溃了

Question

在我的应用程序中，有一个使用相机捕捉图像的工具。在Android6之前的所有版本中，它都能完美地工作，但在Android7.0版本中，它让我的应用程序崩溃了。

<uses-permission android:name="android.permission.CAMERA" />

添加的权限

if (ContextCompat.checkSelfPermission(AddFamilyMemberActivity.this,
                android.Manifest.permission.CAMERA)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(AddFamilyMemberActivity.this,
                    new String[]{android.Manifest.permission.CAMERA},
                    1);
        } else {
            sendToExternalApp();
        }

权限侦听器

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        if (requestCode == 1 && permissions[0].equals(android.Manifest.permission.CAMERA) &&
                grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            sendToExternalApp();
        } else if (requestCode == 1 && permissions[0].equals(android.Manifest.permission.CAMERA) &&
                grantResults[0] == PackageManager.PERMISSION_DENIED) {
            Utilities.showSnackBar("You need to enable camera permission for update profile image", this);
        }
    }

打开相机的代码

protected void sendToExternalApp()
    {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        mProcessingPhotoUri =  getImageFile();
        intent.putExtra(MediaStore.EXTRA_OUTPUT, mProcessingPhotoUri);
        activity.startActivityForResult(intent, REQUEST_CODE_SELECT_IMAGE);
    }

崩溃日志

由：android.content.activityNotFoundException引起：未找到处理意图的活动{act=android.media.action.image_capture flg=0x3 clip={text/uri-list u：file：///storage/emulated/0/dcim/qdhealt/profile.jpg}（有额外内容）}

Answer 1

您的第一个屏幕检查permisson，如下所示

onCreate（或）initialize

if ((ContextCompat.checkSelfPermission(LoginActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED)) {
    requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                    MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
}

下置法

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case PERMISSIONS_CODE:
            if (grantResults.length <= 0 || grantResults[0] != PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(this, "Permission denied", Toast.LENGTH_SHORT).show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
            break;
    }
}
