ACTION_IMAGE_CAPTURE意圖在橫向相機方向上返回時無法恢復onActivityResult上的活動

在編寫問題之前，我進行了大量搜索。我有一個意圖從extra_output從攝像頭中選擇一個圖像存儲在UriACTION_IMAGE_CAPTURE意圖在橫向相機方向上返回時無法恢復onActivityResult上的活動

當圖像被捕獲到肖像和/或沒有自動旋轉完美的作品。但是，如果你在風景和自動旋轉有些模型給我錯誤。

我的意圖代碼：

Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
camera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(imageFile)); 
startActivityForResult(camera, REQUEST_CAMERA);

我onActivityResult片段代碼：

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    ImageView imageFoto = (ImageView) findViewById(R.id.imageIncidenciaDetail); 
    imatgeOriginal = null; 

    if (requestCode == REQUEST_CAMERA && resultCode == RESULT_OK) { 
     //if(imageFile != null) 
     imatgeOriginal = BitmapFactory.decodeFile(imageFile.getAbsolutePath());

我實際上有兩個不同的錯誤：

java.lang.RuntimeException: Unable to resume activity  {com.vicopo.com.lapoblainfo/com.vicopo.com.lapoblainfo.incidencia_detail}:  java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=null} to activity {com.vicopo.com.lapoblainfo/com.vicopo.com.lapoblainfo.incidencia_detail}: java.lang.NullPointerException

而且

和Android清單活動代碼：

<activity 
     android:name=".incidencia_detail" 
     android:label="@string/title_activity_incidencia_detail" 
     android:screenOrientation="portrait" 
     android:configChanges="orientation" 
     >

我可以，如果做一個，並檢查該圖像是不爲空。如果我這樣做的應用程序不會崩潰，但圖像爲空。

在控制權從第三方相機應用程序返回給您之前，您的過程可能會終止。你如何保持'imageFile'，這樣它就不會在這種情況下是'null'？ – CommonsWare 2014-09-04 20:40:13

當你說「圖像爲空」時，你的意思是'imatgeOriginal'或'imageFoto'？ – 2014-09-04 20:44:07

當我說「圖像爲空」時，我的意思是imageFile imageFile是我傳遞給output_extra的文件 imageFoto是一個imageView。這永遠不會爲空，默認情況下，我把一個內部圖像 imageOriginal是一個位圖。我將文件轉換爲位圖當我從相機或圖片庫收到我再次看到我的代碼，我沒有super.onActivityResult.That可能是問題？ – Ausaes 2014-09-04 20:49:43

節省您的Activity的saveInstanceState(Bundle out)的imageFile路徑和恢復imageFile在onCreate(Bundle savedInstanceState)，如果savedInstanceState != null。您可能需要將imageFile作爲String存儲，以便將其保存到Bundle。
