Question

每当我点击导航项目开始活动时，我的应用程序都会崩溃。我在最近6个小时内尝试过类似问题的所有解决方案，但无济于事。包括在manifest中注册活动，将intent (this,menu_profile.class);更改为(mainactivity.this, menu_profile.class); to`（getApplicationContext（），menu_profile.class）;.谷歌许可（13）错误没有解决方案。

段

else if (itemId == R.id.third) {
                    Intent intent = new Intent(getApplicationContext(), Menu_Profile.class);
                    startActivity(intent);
                }

从您的Manifist文件中删除菜单profilr活动中的intent过滤器或替换此

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:theme="@style/AppTheme">

    <activity
        android:name=".MainActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".Menu_Profile"
        android:label="DestinationActivity"/>

</application>

尝试通过侧面导航使用intent启动活动时应用程序崩溃
