pjsip 2.9 中的挂断操作随机应用程序崩溃

Question

我正在尝试通过调用 finish 来关闭我用来制作 voip 的 activity。但我注意到在随机时间而不是关闭电流 activity。它只是关闭整个 Android 应用程序。我也附上了清单中的代码。

    <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:networkSecurityConfig="@xml/network_security_config"


            android:theme="@style/AppTheme">
            <uses-library android:name="org.apache.http.legacy" android:required="false" />

            <activity
                android:name=".FullscreenActivity"
                android:configChanges="orientation|keyboardHidden|screenSize"
                android:label="@string/app_name"
                android:launchMode="singleInstance"
                android:theme="@style/FullscreenTheme">

            </activity>

            <activity
                android:name=".MediaPresentationActivity"
                android:configChanges="orientation|keyboardHidden|screenSize"

                android:label="eFrame"
                android:launchMode="singleInstance"
                android:screenOrientation="landscape"
                android:theme="@style/Theme.AppCompat"
                >



                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.HOME" />
                    <category android:name="android.intent.category.DEFAULT" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>

            </activity>



            <activity
                android:name=".SettingsActivity"
                android:label="@string/title_activity_settings"
                android:parentActivityName=".SettingsActivity"
                android:theme="@android:style/Theme.DeviceDefault">
                <meta-data
                    android:name="android.support.PARENT_ACTIVITY"
                    android:value="org.pjsip.psua2.SettingsActivity" />
            </activity>
            <activity
                android:name=".CallActivity"
                android:configChanges="orientation|keyboardHidden|screenSize"
                android:label="@string/title_activity_call"
                android:theme="@style/Theme.AppCompat.Translucent">

            </activity>


     


        </application>

所以 CallActivity 是我实现 voip 呼叫的 activity。通话结束后，我创建了一个结束按钮来关闭 CallActivity，方法是在某个随机时间从 callActivity.But 调用 hangupcall 函数，它会关闭整个应用程序而不是 CallActivity 。任何帮助将不胜感激

 public void hangupCall(View view)
    {
    finish();
  }

Answer 1

看起来您正在使用一些具有本机代码的库运行。可能本机代码仍然是运行，甚至在您完成 Activity 之后，它正在尝试访问已被垃圾收集器回收的内容。这意味着您需要在完成 Activity.

之前关闭或关闭本机代码中发生的任何事情

查看您正在使用的任何本机库的文档，了解如何释放资源或关闭后台或挂起的操作。

Answer 2

我也遇到了同样的问题。我找不到导致该问题的原因。 call end function 和finish 都是在hangup function 中依次完成的。我所做的是在调用结束函数后在完成函数中创建一个延迟，并且它确实在没有任何进一步的崩溃问题的情况下工作。但是我们会看到结束当前 Activity 的延迟。至少比崩溃好
