Android5.1.+ getRunningAppProcesses()獲取執行中程序（第三方開源庫）
阿新 • • 發佈：2019-02-04
google可能為了安全考慮，在5.1.+後呼叫activitymanager.getRunningAppProcesses（)方法只能返回你自己應用的程序，那如何在5.1.+後獲取執行中程序呢？一個大神stackoverflow給出了答案（點選跳轉）。如果你能熟練的匯入第三方庫，那麼相信你可以不用向下看了，如果你選擇向下看，那我會用白話文教你一步步實現。首先到這位答主的github上下載他上傳的開源庫,梯子自備（點選跳轉）。沒有梯子可以到我的個人百度雲下載：連結:
http://pan.baidu.com/s/1kVjjPsF 密碼: ag6u
下載完成後解壓目錄結構
我們只需要其中的紅線框住的部分，但是直接匯入，肯定會處很多的問題，我們先來處理一部分，開啟libsuperuser
修改完成後來到android studio的project檢視下將他貼上進去
貼上進去肯定會叫你同步，然後就同步羅，會發現一些問題，其中常見的是提示：
Error:(2, 0) Plugin with id ‘com.github.dcendents.android-maven’ not found
Error:(2, 0) Plugin with id ‘com.jfrog.bintray.gradle’ not found
這是因為有兩個外掛我們沒有裝上，我們來到Project下，在那個build.grade裡面新增全域性依賴
將這兩個依賴的外掛寫上，建議寫一個同步一次分兩次進行，第二次下載需要比較長的時間
<code class="hljs cs has-numbering"> <span class="hljs-comment">//自動化maven打包外掛</span>
classpath <span class="hljs-string">'com.github.dcendents:android-maven-gradle-plugin:1.3'</span></code><ul style="" class="pre-numbering"><li>1</li><li>2</li></ul><code class="hljs cs has-numbering"> <span class="hljs-comment">//自動上傳至bintray外掛</span>
classpath <span class="hljs-string">"com.jfrog.bintray.gradle:gradle-bintray-plugin:1.0"</span></code><ul style="" class="pre-numbering"><li>1</li><li>2</li></ul>
填寫好後我們會發現沒有編譯錯誤了，那我們要怎麼去用新增的這個開源庫呢？？來到android檢視下的build.gradle(Module.app)下新增依賴
<code class="hljs bash has-numbering"> compile <span class="hljs-string">'eu.chainfire:libsuperuser:1.0.0.+'</span></code><ul style="" class="pre-numbering"><li>1</li></ul>
重新同步後，我們就可以呼叫裡面的方法了，新建一個ProgressManager類
