如何以编程方式获取当前的android deveice版本(1.5,1.6,2.0等).即我已经在ANdroid 2.2设备中安装了我的apk ..我需要获取设备版本(我的应用程序当前正在运行的android模拟器版本)

wget http://tesseract-ocr.googlecode.com/files/tesseract-3.00.tar.gz
tar -zxvf tesseract-3.00.tar.gz
rm -f tesseract-3.00.tar.gz
git clone https://android.googlesource.com/platform/external/jpeg libjpeg
git checkout e0eadaa39b72e33f032220246c771d7302ebeaf8
cd ..
export TESSERACT_PATH=${PWD}/tesseract-3.00

上面提到的是一些Linux命令.我需要上面提到的相应的Windows命令.请帮忙.

发生异常时,会显示强制关闭和等待的警告对话框.我们可以把它重定向到另一个页面,通过跟踪异常,没有表现出接近这种力量.因为foece后关闭该应用程序会关闭.我们怎样才能阻止.

我想将HTML或MXML文件文档转换为Microsoft .doc和/或.docx格式.

请举例说明这一点？

我需要在单击选项卡时显示进度对话框,

我的代码ID

public class SIPTabWidget extends TabActivity{
 Intent intent;
  @Override
    protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);


    setContentView(R.layout.main);



    final Resources res = getResources(); // Resource object to get Drawables
    final TabHost tabHost = getTabHost(); // The activity TabHost
    TabHost.TabSpec spec; // Reusable TabSpec for each tab



    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, ListContacts.class);

    // Initialize a TabSpec for each tab and add it …

我的代码是:

ListContacts.java

public class ListContacts extends ListActivity {
 @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    System.out.println("List Contacts : onCreate : ");

Cursor cursor = getContentResolver().query(
                ContactsContract.Contacts.CONTENT_URI, null,
                ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null,
                "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");

        startManagingCursor(cursor);

ImageCursorAdapter .java

public class ImageCursorAdapter extends SimpleCursorAdapter implements SectionIndexer{

public View getView(int pos, View inView, ViewGroup parent) {



        View v = inView;
        String phoneNumber = null;
        String contactID = null;

        // Associate the xml file for each row with the …

如何显示9&cent为9¢在Android的编程？

我的代码是:

psmnt = conn.prepareStatement("INSERT INTO upload_data(user_id,photo,audio) " + "values(?,?)");
psmnt.setLong(1, userId);   
fis = new FileInputStream(photoFile);
psmnt.setBinaryStream(2, (InputStream) fis, (int) (photoFile.length()));
fisAudio =  new FileInputStream(audioFile);
psmnt.setBinaryStream(3, (InputStream) fisAudio, (int) (audioFile.length()));
int s = psmnt.executeUpdate();

该type of audio中MYSQL DB是BLOB

例外是:
