Samsung Galaxy 设备 Camera Intent 问题

Question

得到

以下错误：-

make sure class name exists is public and has an empty constructor that is public android

调用时

  Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, CAMERA_CODE);

我想要相机意图的银河设备示例，请任何人就三星设备问题提供帮助！

注意：- 它可能正在重新创建 activity，最后有时应用程序会崩溃，或者无法获取图像，所以请帮助我！

堆栈跟踪：-

java.lang.RuntimeException: Unable to start activity ComponentInfo{MYActivity}: android.app.Fragment$InstantiationException: Unable to instantiate fragment MYFragment: make sure class name exists, is public, and has an empty constructor that is public at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2693) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2758) at android.app.ActivityThread.access0(ActivityThread.java:177) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1448) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:145) at android.app.ActivityThread.main(ActivityThread.java:5942) at java.lang.reflect.Method.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1388) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1183)

Answer 1

某处，你有一个片段。作为重新创建 activity 的一部分，框架无法实例化该片段。或者：

您的片段是内部 class（即，不是常规 Java class 或 static 嵌套 class） , 或
您的片段不是public或
您的片段没有零参数 public 构造函数

Answer 2

自己找到答案这是最好的例子，它是自己为设备烦恼！

AndroidCameraUtils - 下载项目 并从库项目中包含它，下面是您可以使用的代码片段！

 private void setupCameraIntentHelper() {
    mCameraIntentHelper = new CameraIntentHelper(this, new CameraIntentHelperCallback() {
        @Override
        public void onPhotoUriFound(Date dateCameraIntentStarted, Uri photoUri, int rotateXDegrees) {
            messageView.setText(getString(R.string.activity_camera_intent_photo_uri_found) + photoUri.toString());

            Bitmap photo = BitmapHelper.readBitmap(CameraIntentActivity.this, photoUri);
            if (photo != null) {
                photo = BitmapHelper.shrinkBitmap(photo, 300, rotateXDegrees);
                ImageView imageView = (ImageView) findViewById(de.ecotastic.android.camerautil.sample.R.id.activity_camera_intent_image_view);
                imageView.setImageBitmap(photo);
            }
        }

        @Override
        public void deletePhotoWithUri(Uri photoUri) {
            BitmapHelper.deleteImageWithUriIfExists(photoUri, CameraIntentActivity.this);
        }

        @Override
        public void onSdCardNotMounted() {
            Toast.makeText(getApplicationContext(), getString(R.string.error_sd_card_not_mounted), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onCanceled() {
            Toast.makeText(getApplicationContext(), getString(R.string.warning_camera_intent_canceled), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onCouldNotTakePhoto() {
            Toast.makeText(getApplicationContext(), getString(R.string.error_could_not_take_photo), Toast.LENGTH_LONG).show();
        }

        @Override
        public void onPhotoUriNotFound() {
            messageView.setText(getString(R.string.activity_camera_intent_photo_uri_not_found));
        }

        @Override
        public void logException(Exception e) {
            Toast.makeText(getApplicationContext(), getString(R.string.error_sth_went_wrong), Toast.LENGTH_LONG).show();
            Log.d(getClass().getName(), e.getMessage());
        }
    });
}

@Override
protected void onSaveInstanceState(Bundle savedInstanceState) {
    super.onSaveInstanceState(savedInstanceState);
    mCameraIntentHelper.onSaveInstanceState(savedInstanceState);
}

@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
    mCameraIntentHelper.onRestoreInstanceState(savedInstanceState);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    mCameraIntentHelper.onActivityResult(requestCode, resultCode, intent);
}
}

将以下行添加到您的 activityandroid:configChanges="keyboardHidden|orientation|screenSize"

注意:- 我尝试了很多相机实用程序的例子，当然还有其他方法来处理它，但对于初学者和不太熟悉核心概念的人来说会对这个项目更满意。谢谢！
