标签： java android android-intent

我在尝试启动除MainActivity之外的其他活动时不断遇到安全异常，当我启动MainActivity时代码运行正常但在我尝试启动其他任何其他活动时抛出异常比起MainActivity，我一直在寻找答案并得到一个解决方案来放-android：exported =＆＃34; true＆＃34; - 在我的Manifest中，但是这并没有帮助我解决这个问题。面对，任何帮助到目前为止将受到高度赞赏。

替换

<activity android:name=".registration">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER"/>
                <category android:name="android.intent.category.DEFAULT"/>
            </intent-filter>
        </activity>

带

<activity android:name="com.infamuspips.cess.registration">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
