MainActivityicon does not exist in com.packagename

[lntsudhakar]

I'm trying to run in android, but I'm getting the following error.

AndroidManifest.xml

<activity
          android:name=".SplashActivity"
          android:theme="@style/SplashTheme"
          android:label="@string/app_name"
          android:exported="true">
        </activity>

      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|screenSize"
        android:windowSoftInputMode="adjustNothing"
        android:exported="true"
        android:screenOrientation="sensorPortrait">
      </activity>
      <activity-alias
            android:name="com.package.MainActivityicon"
            android:enabled="true"
            android:icon="@mipmap/icon"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>

        <activity-alias
            android:name="com.package.MainActivityic"
            android:enabled="false"
            android:icon="@mipmap/ic"
            android:targetActivity=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity-alias>

Error

@lntsudhakar, I think it is a simple package name mismatch, in the AndroidManifest.xml file the package name is com.package whereas in the error it is com.packagename.

[lntsudhakar]

No I changed the actual package name to sample com.package. Both are same in my file.

@lntsudhakar, Please share some more details so that I can pinpoint the issue.

1. What React-Native version are you using?
2. Are you using the latest version of this package?
3. Is the Java package name the same as the package name in AndroidManfest.xml?
4. Can you please share the android/app/build.gradle file?

[lntsudhakar]

It was the package name different in gradle file. Now its fixed.
