I am creating and Android plugin and I’m trying to use the Log method instead of the log xml element in an _APL.xml or _UPL.xml file, but I get an error that it cannot find the symbol.

UATHelper: Packaging (Android (ASTC)):   Z:\app\src\main\java\com\epicgames\ue4\GameActivity.java:3263: error: cannot find symbol
UATHelper: Packaging (Android (ASTC)):           Log.i(TAG, "GameActivity::OnResume()");
UATHelper: Packaging (Android (ASTC)):              ^
UATHelper: Packaging (Android (ASTC)):     symbol:   method i(String,String)
UATHelper: Packaging (Android (ASTC)):     location: variable Log of type Logger
PackagingResults: Error: cannot find symbol

My code:

<gameActivityImportAdditions>
<insert>
    import android.util.Log;
</insert>
</gameActivityImportAdditions>

<gameActivityOnResumeAdditions>
<insert>
    <![CDATA[
    final String TAG = "UNREAL";
    Log.i(TAG, "GameActivity::OnResume()");
    ]]>
</insert>
</gameActivityOnResumeAdditions>

You can see an example in this plugin: [Plugin][Free] Mobile Native Code Plugin for Unreal Engine 4 (JNI/Obj-c) - Community Content, Tools and Tutorials - Unreal Engine Forums

if you are using like below code

<gameActivityImportAdditions>
    <insert>
        ...
        import android.util.Log;
    </insert>
</gameActivityImportAdditions>

<gameActivityClassAdditions>
    <insert>
        ...
        public void logVerbose(String tag, String msg) { Log.v(tag, msg); }
        public void logDebug(String tag, String msg) { Log.d(tag, msg); }
        public void logInfo(String tag, String msg) { Log.i(tag, msg); }
        public void logWarn(String tag, String msg) { Log.w(tag, msg); }
        public void logError(String tag, String msg) { Log.e(tag, msg); }
        public void logAssert(String tag, String msg) { Log.wtf(tag, msg); }

convert code like below

<gameActivityClassAdditions>
    <insert>
        ...
        public void logVerbose(String tag, String msg) { android.util.Log.v(tag, msg); }
        public void logDebug(String tag, String msg) { android.util.Log.d(tag, msg); }
        public void logInfo(String tag, String msg) { android.util.Log.i(tag, msg); }
        public void logWarn(String tag, String msg) { android.util.Log.w(tag, msg); }
        public void logError(String tag, String msg) { android.util.Log.e(tag, msg); }
        public void logAssert(String tag, String msg) { android.util.Log.wtf(tag, msg); }

this will solve the problem
because i think there is other class Name Log according to error log from ue

UATHelper: Packaging (Android (ASTC)): location: variable Log of type Logger
