android-studio - Android AndroidManifest 文件中 改变程序主入口的问题。

Question

我的程序本来是将MainActivity作为程序主入口，代码如下

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="xxxxxxxxxxxxxxxxxxxx" />

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

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

        </activity>

        <activity android:name=".activity.SearchActivity" />


        <activity android:name=".activity.LoginActivity" />


        <activity android:name=".activity.RegisterActivity"/>

        <service
            android:name="com.baidu.location.f"
            android:enabled="true"
            android:process=":remote" />

    </application>

现在想将 LoginActivity 作为程序的主入口，将代码改成这样

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data
            android:name="com.baidu.lbsapi.API_KEY"
            android:value="xxxxxxxxxxxxxxxxxx" />

        <activity
            android:name=".activity.MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">


        </activity>

        <activity android:name=".activity.SearchActivity" />


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

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


        <activity android:name=".activity.RegisterActivity"/>

        <service
            android:name="com.baidu.location.f"
            android:enabled="true"
            android:process=":remote" />

    </application>

结果现在一安装运行就提示 程序已停止运行

Answer 1

Where is your error log? In theory, there will be no problem simply changing the entry. Your LoginActivity should be abnormal.

Answer 2

I agree with the opinion above. It should not be a problem with the registration file, but an exception in the java code.

Look at the error log exported by logcat and upload it.

Answer 3

How to solve the problem if there is no log/...

Answer 4

Post the log for everyone to see
