源代碼：

FileOutputStream fileOutputStream=null;
try {
	fileOutputStream = mActivity.openFileOutput("share.png",1);
} catch (FileNotFoundException e) {
	e.printStackTrace();
}

意思是MODE_WORLD_READABLE 模式已經被廢棄。將1修改爲MODE_PRIVATE

四種模式，分別爲： 

Context.MODE_PRIVATE    = 0
Context.MODE_APPEND    = 32768
Context.MODE_WORLD_READABLE = 1
Context.MODE_WORLD_WRITEABLE = 2

所以修改代碼如下：

FileOutputStream fileOutputStream=null;
try {
	fileOutputStream = mActivity.openFileOutput("share.png",MODE_PRIVATE);
} catch (FileNotFoundException e) {
	DebugLog.d(TAG,"File Not Found Exception");
	e.printStackTrace();
}

修改之後完美解決問題；
