【问题描述】：

我已经好几天在寻找这个问题的解决方案，但我不知道该怎么办:(

我有一个使用本机相机拍照的应用程序，但问题是，有时，并且仅在某些设备上，当我拍照并保存并返回时，我的应用程序会重新启动。

它是一个webview，所以它的大部分逻辑都是在服务器端制作的，但是使用javascript接口来处理相机等本机功能。

它很难捕捉，因为它只发生在某些设备上，即使它们是相同的型号，我有两个 Galaxy ace，一个几乎总是发生，另一个很少发生（这些不是唯一的设备我已经测试过）

我认为这与相机的方向或类似的东西有关。因为当我在保存/丢弃屏幕中旋转设备时（拍照后）似乎更频繁地发生

这是我的一些代码：

清单：

        <activity
        android:name="XXX"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:excludeFromRecents="false"
        android:label="@string/XXX"
        android:launchMode="singleTask"
        android:taskAffinity=""
        android:windowSoftInputMode="adjustPan" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

相机类

        public void showNativeCamera()

         // create Intent to take a picture and return control to the calling application
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);


        UUID uniqueKey = UUID.randomUUID();
        mPictureName = "img_" + uniqueKey.toString() + ".jpg"; 
        fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
        Log.d("amanda", "file uri: " + fileUri);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name


        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        // start the image capture Intent
        mParent.startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

【问题讨论】：

嗨，你有你的解决方案吗？

@AnjaliTripathi 老实说不记得了，我在 5 年半前问过这个问题。

【参考方案1】：

你能显示你在onActivityResult 中的代码吗？

随机猜测：如果你在onActivityResult 中使用mPictureName，那么如果活动在后台被破坏，你必须确保你的类的字段被恢复。
