当前应用的版本比较：

 

 private boolean setVersion(){
    	
    	String version = "";
		try {
			version = getPackageManager().getPackageInfo(VersionCompareActivity.this.getPackageName(), 0).versionName;
		} catch (NameNotFoundException e) {
			e.printStackTrace();
		}
		Log.d("test", "_version__" + version);
    	if(!TextUtils.isEmpty(version)){
    		int code = version.compareTo("1.2.3");
    		 Log.d("test", "_code__" + code);
    		if(code > 0){
    			return true;
    		}
    	}
    	return false;
    }
