我遇到了麻烦，这个代码在 android 2.3 中运行完美，但是在 4.2 中我看到一个空白活动，而我的线程正在工作，在 2.3 中，我用我的微调器和所有东西正确地看到了活动。
String upLoadServerUri = null;
String MAIL = null;
int serverResponseCode = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_upload_to_server);
Bundle extras = getIntent().getExtras();
//String MAIL = extras.getString("mail");
if (extras != null) {
MAIL = extras.getString("mail");//usuario
}
//uploadButton = (Button)findViewById(R.id.uploadButton);
//messageText = (TextView)findViewById(R.id.messageText);
/************* Php script path Receiver****************/
upLoadServerUri = "http://www.mydomain.com/scripts/Receiver.php";
//final File folder = new File(Environment.getExternalStorageDirectory() + File.separator +"WhatsApp"+ File.separator +"Databases" + File.separator);
final File folder = new File(Environment.getExternalStorageDirectory().toString());
File dir = new File(folder.toString());
boolean exists = dir.exists();
if (!exists) {
// Thread.currentThread().interrupt();
Log.v("ARCHIVOS NO ENCONTRADOS", folder.toString());
Intent i=new Intent(UploadToServer.this, NoFiles.class);
startActivity(i);
return;
}
Thread threadMenu = new Thread(new Runnable() {
public void run() {
runOnUiThread(new Runnable () {
public void run() {
try {
Log.v("TOUX", folder.toString() );
//Log.v("TOUX", Environment.getExternalFilesDir().toString() );
uploadFile(folder + "/file.png");
} catch (Exception e) {
} finally {
finish();
Intent i=new Intent(UploadToServer.this, AllOK.class);
startActivity(i);
Thread.currentThread().interrupt();
}
}
});
}
});
threadMenu.start();
}
这是我的布局文件
