獲取Android版本號跟識別是debug包還是release包

//版本名  versionName
public static String getVersionName(Context context) {  
        return getPackageInfo(context).versionName;  
}  

//版本號  versionCode
public static int getVersionCode(Context context) {  
        return getPackageInfo(context).versionCode;  
}  

private static PackageInfo getPackageInfo(Context context) {  
        PackageInfo pi = null;  
        try {  
	    PackageManager pm = context.getPackageManager();  
	    pi = pm.getPackageInfo(context.getPackageName(),  
	        PackageManager.GET_CONFIGURATIONS);  
		return pi;  
	    } catch (Exception e) {  
	        e.printStackTrace();  
	    }  
	    return pi;
	}
		return pi;  
	    } catch (Exception e) {  
	        e.printStackTrace();  
	    }  
	    return pi;
	}

識別debug

public static boolean isDebug() {
        try {
            ApplicationInfo info = context.getApplicationInfo();
            return (info.flags & ApplicationInfo.FLAG_DEBUGGABLE) != 0;
        } catch (Exception e) {
            return false;
        }
        //return "debug".equals(channel);
    }
