android studio 使用Mocklocation虛擬定位

首先需要在 AndroidManifest.xml 檔案中新增「獲取模擬定位資訊」許可權。

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
 
 <uses-permission android:name="android.permission.INTERNET"/>
 <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
 <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"
  tools:ignore="MockLocation"/>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAG"/>

然後需要開啟android studio模擬器的開發者許可權

step1:找到安卓的setting點開

step2:拉到最底部,點選System,再拉到最底部找到關於手機,手機版本連續點選7次,返回上一層就有一個開發者選擇

step3:點選Developer options,往下拉,找到select mock location app,點選你需要模擬定位的app就行了。

具體app的程式碼,我直接貼出來了
