根据这个答案如何解决"你的APK的版本代码需要高于2".在Google Play的开发者控制台中？我刚刚将版本代码从2更改为3,但无法上传构建版本.

在我上传apk之前,这是我的旧清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="mypackage name"
    android:installLocation="auto"
    android:versionCode="28"
    android:versionName="1.0028" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
        .....

这是我必须在Android开发者控制台上传的新版本代码.看我的清单

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="mypackage name"
    android:installLocation="auto"
    android:versionCode="2"
    android:versionName="2.0001" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />
        ......

我不知道这个问题是什么.有帮助吗？

找不到活动来处理Intent错误？它将如何解决.

Preference customPref = (Preference) findPreference("DataEntryScreen"); 
   customPref
        .setOnPreferenceClickListener(new OnPreferenceClickListener() {
         public boolean onPreferenceClick(Preference preference) {                  

        Intent i = new Intent("com.scytec.datamobile.vd.gui.android.AppPreferenceActivity");
                 startActivity(i);
                  return true;                                        
               }
           });

我的应用程序运行良好的所有Android版本但我注意到在Android 8.1.0(奥利奥)当我从纵向活动到横向活动的屏幕,当我按回按钮它显示异常行为.

屏幕从横向自动旋转并将其恢复正常.看起来Activity正在重新启动.

以下是清单文件中定义的活动.

<activity
    android:name=".Home.TrainingsActivity"
    android:configChanges="keyboardHidden|orientation|screenSize|layoutDirection|locale"
    android:screenOrientation="portrait" />

<activity
    android:name=".Home.ProgrammeActivity"
    android:configChanges="keyboardHidden|orientation|screenSize|layoutDirection|locale"
    android:screenOrientation="landscape" />

在设置内容视图时,我遇到了这个异常.我已经尝试通过以下方式处理此异常:

try{
     setContentView(R.layout.activity_main);

}catch (OutOfMemoryError e) {
        e.printStackTrace();
    }

在测试时,这个例外在100次约为5次.但我无法解决这个问题.或者我的QA团队将在此杀死我:(

我正在使用此代码.我需要合并两个视频.它将所有视频保存在临时文件夹中,但未保存在合并条件下.Append和DoAppend是我想要合并视频的功能.

public String append(ArrayList<String> trimVideos) {

        for (int i = 0; i < trimVideos.size() - 1; i++) {

      String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
     if (i == 0) {                      
            String OutPutFileName = Constants.STORAGE_VIDEO_TEMP_PATH +                           
            File.separator + "APPEND" + "_" + timeStamp + ".mp4";
            doAppend(trimVideos.get(0), trimVideos.get(i + 1),OutPutFileName);
            Log.e(Constants.TAG, "In First: " + i + " " +   OutPutFileName);

                  } else {

        String OutPutFileName = Constants.STORAGE_VIDEO_TEMP_PATH
    + File.separator + "APPEND" + i + "_" + timeStamp + ".mp4";
                    doAppend(lastAppendOut, trimVideos.get(i + …

的Exception:

Unable to start activity ComponentInfo{com.scytec.datamobile.vd.gui.android/com.scytec.datamobile.vd.gui.android.SelectedList}: java.lang.NullPointerException.. 我只想显示复选框列表视图,并在每次检查时显示"已检查",但我不知道为什么这会给我一个例外.

public class SelectedList extends Activity implements IObserver{

        private ListView machine_listview;
        ArrayAdapter<String> adapter;
        ArrayList<String> arrayListofMachines;
        ArrayList<String> arrayListofMachineNumbers;
        Vector<MDCMachineStatus> machineStatus_vector;
        Handler handler;

        private static int oldPosition = 0;
        private Boolean firstClick = true;




        @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.machinelistview);

            machine_listview = (ListView) findViewById(R.id.machine_listview);
            machine_listview.setFastScrollEnabled(true);

            MachineStatusSingleton.Register(this);

            getData();

            adapter = new ArrayAdapter<String>(SelectedList.this, R.layout.selectedlist,R.id.text1, arrayListofMachines);

            machine_listview.setAdapter(adapter);

            machine_listview.setSelection(oldPosition);


            CheckBox chk=(CheckBox)findViewById(R.id.check);
            chk.setOnCheckedChangeListener(new OnCheckedChangeListener()

当我从服务中获取html文本时,我需要在文本View上显示文本.

Managing Safely <b> End Of Course Theory Test </b> <span style="color:red;"> part1 </span>

我正在设置这个文本

tv.settext(Html.fromHTML("Managing Safely <b> End Of Course Theory Test </b> <span style="color:red;"> part1 </span>"));

它显示粗体但不显示红色文本.

我在linux上用libx264编译了ffmpeg,现在当我运行这个命令时

String[] ffmpegCommandImages = {
                    "/data/data/uk.org.humanfocus.hfi/ffmpeg",
                    "-i", videoPath,
                    "-b:v", "1000k",
                    "-vf", "scale=-1:576",
                    "-c:a", "copy",
                     "-c:v", "libx264", 
                    "-threads", "12",
                    "-b:a", "196k",
                    to };

这是我得到的错误,发布日志...
请帮帮我.
