Follow you splash scrren blog to do,but have a problem(Android)

happyphper commented 4 years ago

In Android，from step 1 to 4,I did these, but have a problem is that:

/Users/happyphper/workspace/rrcp_flutter/android/app/src/main/java/com/example/rrcp_flutter/MainActivity.java:17: error: incompatible types: MainActivity cannot be converted to FlutterEngine
    GeneratedPluginRegistrant.registerWith(this);
                                           ^
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output
1 error

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.
...

I clone you project to local and All is right.

So I compare android your directory to my directory,

I find a android/app/src/main/AndroidManifest.xml and android/app/build.gradle are different, the difference is that

# AndroidManifest.xml
...
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
...

# build.gradle
...
...
apply plugin: 'com.android.application'
+ apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
...
dependencies {
+ implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    ...
}
...

this is flutter auto created, maybe the result is different version.

put this code to your project, and the error occurred.

I can't solve this problem, Could you have any solution?

what's the code of your MainActivity.java ?

happyphper commented 4 years ago

@diegoveloper The MainActivity.java is not auto created. So I copy your code the android/app/src/main/java/com/example/rrcp_flutter/MainActivity.java. code is same. like this

package com.example.rrcp_flutter;

import android.os.Bundle;
import io.flutter.app.FlutterActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;

import android.view.ViewTreeObserver;
import android.view.WindowManager;

public class MainActivity extends FlutterActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //make transparent status bar
    getWindow().setStatusBarColor(0x00000000);
    GeneratedPluginRegistrant.registerWith(this); 
    //Remove full screen flag after load
    ViewTreeObserver vto = getFlutterView().getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override
      public void onGlobalLayout() {
        getFlutterView().getViewTreeObserver().removeOnGlobalLayoutListener(this);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
      }
    });
  }
}

Actually, you don't need to modify the MainActivity , remove that class, just use the classes generated using flutter create .

happyphper commented 4 years ago

Thanks a lot.

I create a new project, and use the flutter_native_splash to create android native splash.

I found there are something differences between new project and old project. then compare with these, I solved this problem.

and for IOS, I used xcode to adjust the size.

Use Xcode To Adjust Native Splash Screen
