处理传的地址有空格以及调试的使用debug

通常我们在传递一个地址时如果有空格

String myString = "http://myhost.com/media/mp3s/9/Agenda of swine - 13. Persecution Ascension_ leave nothing standing.mp3" ;  
URI myUri = new URI ( myString );  
结果会抛出异常

java . net . URISyntaxException : Illegal character in path at index X 

 

其实很简单 只要把空格转换成别的字符就可以了

这里加设有空格的只在最后一个\ 后面

URI uri = new URI ( string . replace ( ' ' , '+' ));  
或者

URI uri = new URI ( string . replace ( " " , "%20" ));  
然后

int pos = string . lastIndexOf ( '/' ) + 1 ;  
URI uri = new URI ( string . substring ( 0 , pos ) + URLEncoder . encode ( string . substring ( pos ), "UTF-8" ));  

2.

<application android:icon = "@drawable/icon"  
    android:name = ".SomeApp"  
    android:label = "@string/app_name" android:debuggable = "true" >  
if ( Log . isLoggable ( TAG , Log . DEBUG )) {  
    Log . d ( TAG , "some log statement" );  
}

 

3. 在一个服务中调试 有时候断电不能固定

android.os .Debug .waitForDebugger ( ) ;

public
 
class
 SoftKeyboard 
extends
 InputMethodService
        implements
 KeyboardView.OnKeyboardActionListener {

    @Override
        public
 
void
 onConfigurationChanged(Configuration newConfig) {
        Log.d("SoftKeyboard"
, 
"onConfigurationChanged()"
);

        /* now let's wait until the debugger attaches */
        android.os.Debug.waitForDebugger();

        super
.onConfigurationChanged(newConfig);

        /* do something useful... */

        }
