我正在尝试将PNG文件转换为单片视频片段,以便在项目中启动.

我有什么代码来实现它是: -

private boolean MediaConversion()
    {
        MediaCodec codec = MediaCodec.createEncoderByType(MIMETYPE);
        MediaFormat mediaFormat = null;
        if(CamcorderProfile.hasProfile(CamcorderProfile.QUALITY_720P)){
            mediaFormat = MediaFormat.createVideoFormat(MIMETYPE, 1280 , 720);
        } else {
            mediaFormat = MediaFormat.createVideoFormat(MIMETYPE, 720, 480);
        }

        mediaFormat.setInteger(MediaFormat.KEY_BIT_RATE, 700000);
        mediaFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 10);
        mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT, MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420SemiPlanar);
        mediaFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 5);
        codec.configure(mediaFormat, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);

        codec.start();

        ByteBuffer[] inputBuffers = codec.getInputBuffers();
        ByteBuffer[] outputBuffers = codec.getOutputBuffers();
        boolean sawInputEOS = false;
        int inputBufferIndex= -1, outputBufferIndex= -1;
        BufferInfo info=null;        

        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        Bitmap bitmap = null;
        try {
        bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.image);                    
            Log.e("Uploaded", "Bitmap:" …

我的应用程序在Android OS Lollipop中运行时,后台出现以下异常.无法在我的代码中弄清楚它的确切位置或对它的任何引用.

以前有人遇到过吗？

我想在数据库中保存工作日,所以我想通过为每天分配int值来存储它.即

1 - >选中, 0 - >未选中.

星期一= 0/1

星期二= 0/1

.....

星期日= 0/1.

但这将在DB中生成 7列.所以我想如果我将它存储在一个数组中并检索值以供进一步使用,是否有人可以帮助我.我正在通过互联网阅读一些例子,但没有轻易得到它.

我正在尝试在Android WebView中使用CSS3动画,但是在启动动画时(大约500ms)我会遇到非常恼人的延迟.

动画运行平稳,无滞后,但开始时有延迟.由于没有滞后,我认为这不是性能问题.或者它可能是？

这不是默认的300ms onclick延迟,我已经改为ontouchstart,当我做除了动画/过渡之外的任何事情时,没有延迟.只有这两个.

它也不是动画延迟属性,我已经将它设置为0.

任何可能的解释/解决方案

PS:我正在尝试运行的动画/转换是transform: translateX()属性.之前,我正在尝试left: Xpx,但它在动画期间滞后.随着变换,没有滞后,但有延迟.

我已经解决了这个问题,它适用于使用SSL的自己的情况

而且我也尝试过这个,它在某种程度上符合我的需要,但在我的情况下它不起作用.

我也阅读了这个主题,但仍然无法在我的代码中不使用SSL发送电子邮件.

每次我发邮件都说"例外554,拒绝邮件"

我真正需要的是使用::

mailhost:"smtpout.secureserver.net"

港口号:25

谢谢,

HAPS.

我已经在我的Android应用程序中集成了Quickblox SDK V2.2.5以与Social Integration Twitter一起工作,但它会抛出错误:'{"errors":["Bad Authentication data"]}'

以下是我的代码: -

// If in the below code I use static TOKEN & TOKEN-SECRET generated by my iOS app then it works well, whereas it is not working with Android generated TOKEN & its SECRET.

QBUsers.signInUsingSocialProvider(QBProvider.TWITTER,
    preferences.getTwitterToken().trim(),
    preferences.getTwitterTokenSecret().trim(),
    new QBEntityCallbackImpl<QBUser>() {
        @Override
        public void onSuccess(QBUser user, Bundle args) {
            Log.d("Login was successful", "user: " + user.toString());          
            }

        @Override
        public void onError(List<String> errors) {
            Log.e("Twitter Login", "Error: " + …

当我在 Apache flink 中运行SocketWindowWordCount程序时，它显示一个

我正在尝试使用"位置名称"(即"国家/地区名称")将MapView中的动画设置为某个位置.我得到了例外:

如果你看不到pic那么异常是:: IOException:服务不可用有错误无法获得连接工厂客户端.

我使用的代码如下:

public class ShowMapView extends MapActivity
{
    MapView mapView;
    MapController mapController;

String Country;

@Override
public void onCreate(Bundle bundleMap)
{
    super.onCreate(bundleMap);
    setContentView(R.layout.show_map);

    mapView = (MapView)findViewById(R.id.MapView);

    LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);
    View zoomView = mapView.getZoomControls();

    zoomLayout.addView(zoomView,
            new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT));
    mapView.setBuiltInZoomControls(true);


    Intent intent = this.getIntent();
    Country = intent.getStringExtra("Country");

    Geocoder geocoder = new Geocoder(this, Locale.getDefault());
    Log.v("GEOCODER", geocoder.toString());

    try
    {
        Log.v("MAP", "TRY BLOCK");
        List<Address> address = geocoder.getFromLocationName(Country, 2);
        Log.v("MAP", "Country: "  + Country);
        if(address.size() > 0)
        { …

我从Web服务中获取GridView的图像和文本,因此需要一些时间来显示GridView.我想显示一个ProgressDialog,直到Grid完全加载.我到现在所做的如下:

public class PCGridMain extends Activity
{
    WebService web = new WebService();
    private GridView gridView;
    ProgressDialog dialog;
    Bitmap icon;


    int i, total;
    URL url= null;
    List<GridItem> list;

    @Override
    public void onCreate(Bundle grid)
    {
        super.onCreate(grid);
        dialog = ProgressDialog.show(PCGridMain.this, "Loading...", "Loading App, Please wait.", true);
        DialogWork dWork = new DialogWork();
        dWork.execute();

        setContentView(R.layout.main);
        gridView = (GridView)findViewById(R.id.gridView1);

        web.WebService1();       
        total = web.totalService;        



        list = new ArrayList<GridItem>();

        for(i=0; i<total; i++)
            {
                    Log.v("Try Block", "See what we get:-");
                    try 
                    {
                        Log.v("GridMain", "try url"  + Integer.toString(i));
                        url = …
