主线程显示网络图片：

	public static Bitmap GetInternetBitMap(String _url) {
		StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork().penaltyLog().build());		
		Bitmap bitmap = null;
		try{
			HttpURLConnection conn = (HttpURLConnection)(new URL(_url).openConnection());
			conn.connect();
			if(conn.getResponseCode()==200){
				InputStream input = conn.getInputStream();
				bitmap = BitmapFactory.decodeStream(input);
				input.close();
			}
		}catch(Exception e){
			e.printStackTrace();
		}
		return bitmap;	
    }

子线程显示网络图片：

	public static void GetHttpBitMap(final String url,final Handler handle,final boolean timeout) {
		new Thread(){
			@Override
			public void run() {
				  try {				  
					    DefaultHttpClient dhc = new DefaultHttpClient();
					    if(timeout){
					    	dhc.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 2000); //请求超时时间
					    	dhc.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 2000); //等待数据时间
					    }
			            handle.obtainMessage(1,BitmapFactory.decodeStream(dhc.execute(new HttpGet(url)).getEntity().getContent())).sendToTarget();				  					
				  }catch (Exception e) { handle.obtainMessage(0,"服务器出错，请稍候重试！").sendToTarget();}
			}
		}.start();		
    }

本地上传图片正常，发布版点击图片上传没反映？

解决：“代码混淆”功能导致的问题，需在proguard-project.txt中加入：

-keepclassmembers class * extends android.webkit.WebChromeClient {public void openFileChooser(...);}
