美元代碼無法正常工作

Question

我在按鈕上有一個ussd代碼。我在清單中添加了CALL_PHONE權限。 我使用了api（23）。 此代碼無法正常工作

基本上我應該做什么？ 我有以下錯誤：

E / AndroidRuntime：致命例外：主進程：com.mahdishekari.mycollectbill，PID：31738 java.lang.SecurityException：權限拒絕：啟動Intent {act = android.intent.action.CALL dat = tel：xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx cmp = com。來自ProcessRecord {4e2904f 31738：com.mahdishekari.mycollectbill / u0a109}（pid = 31738，uid = 10109）的android.server.telecom / .components.UserCallActivity}，具有在android.os.Parcel.readException上的android.permission.CALL_PHONE權限被撤消（android.os.Parcel.readException（Parcel.java:1573）位於android.app.ActivityManagerProxy.startActivity（ActivityManagerNative.java:2776）位於android.app.Instrumentation.execStartActivity（Instrumentation.java： 1509）位於android.app.Activity.startActivityForResult（Activity.java:3958）位於android.app.Activity.startActivityForResult（Activity.java:3919）位於com.mahdishekari.mycollectbill.ActivityMain $ C00661.onClick（ActivityMain.java:78 ），位於android.view.Vie的android.view.View.performClick（View.java:5217） w $ PerformClick.run（View.java:21349）在android.os.Handler.handleCallback（Handler.java:739）在android.os.Handler.dispatchMessage（Handler.java:95）在android.os.Looper.loop （Looper.java:148）在android.app.ActivityThread.main（ActivityThread.java:5585）在java.lang.reflect.Method.invoke（本機方法）在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run （ZygoteInit.java:730），位於com.android.internal.os.ZygoteInit.main（ZygoteInit.java:620）I / Process：正在發送信號。 PID：31738 SIG：9與目標VM斷開連接，地址：'localhost：8601'，傳輸：'socket'

Answer 1

在android> 23中，您必須在運行時檢查權限

在運行時請求權限

Answer 2

在清單中，您已經聲明要向用戶請求這些權限。 但是，您必須了解，僅通過在Manifest中聲明它們，您實際上並沒有獲得這些權限。 您需要在運行時請求這些權限。

從Android 6.0（API級別23）開始，用戶可以隨時撤消任何應用程序的權限，即使該應用程序定位於較低的API級別也是如此。 因此，即使該應用昨天使用了相機，也無法假設它今天仍然具有該權限。

資料來源： 官方網站

我還沒有完全通過您的代碼。 但是，關於解決您所發布的錯誤，解決方案非常簡單。 您需要做的就是在運行時請求android.permission.CALL_PHONE 。

最好的指南可能是官方網站 。 只需閱讀10分鍾即可。
