dependencies {implementation fileTree(dir:'libs',include:['*.jar','*.aar'])}

如下图所示：

在项目中新建一个 Empty Views Activity进行SDK的测试：

命名为 MainActivity，并勾选为启动 Activity ：

• activity_main.xml

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/main"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><Buttonandroid:id="@+id/button"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="40dp"android:text="跳转SDK"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toTopOf="parent"/><TextViewandroid:id="@+id/textView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="20dp"android:padding="15dp"android:text="这里是MainActivity"android:textSize="16sp"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toBottomOf="@id/button"/></androidx.constraintlayout.widget.ConstraintLayout>

• MainActivity.java

packagecom.example.myapplication;importandroid.content.Intent;importandroid.os.Bundle;importandroid.view.View;importandroid.widget.Button;importandroid.widget.TextView;importandroid.widget.Toast;importandroidx.activity.EdgeToEdge;importandroidx.appcompat.app.AppCompatActivity;importandroidx.core.graphics.Insets;importandroidx.core.view.ViewCompat;importandroidx.core.view.WindowInsetsCompat;importcom.example.mylibrary.OneActivity;publicclassMainActivityextendsAppCompatActivityimplementsView.OnClickListener{privateButtonmButton;privateTextViewmTextView;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);EdgeToEdge.enable(this);setContentView(R.layout.activity_main);ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main),(v,insets)->{InsetssystemBars =insets.getInsets(WindowInsetsCompat.Type.systemBars());v.setPadding(systemBars.left,systemBars.top,systemBars.right,systemBars.bottom);returninsets;});initView();}privatevoidinitView(){mButton =findViewById(R.id.button);mButton.setOnClickListener(this);mTextView =findViewById(R.id.textView);mTextView.setOnClickListener(this);}@OverridepublicvoidonClick(Viewview){intid =view.getId();if(id ==R.id.button){startActivity(newIntent(this,OneActivity.class));}elseif(id ==com.example.mylibrary.R.id.textView){Toast.makeText(this,mTextView.getText(),Toast.LENGTH_SHORT).show();}}}

MainActivity 中存在一个按钮，点击跳转SDK中的 OneActivity 页面，效果如下：

至此，我们完成了 Android SDK 的制作和使用。Android SDK的开发

新建项目，如果选择 Empty Activity 的话语言默认是 Kotlin，此处选择 No Activity：

本教程使用 Java 语言，构建配置语言为 Groovy，可自行决定：

等待项目编译完成，在新的项目中创建Module：

选择 Android Library：

根据自己的需求编写SDK，此处新建 Empty Views Activity：

命名为 OneActivity：

再新建一个 Empty Views Activity命名为 TwoActivity：

做一个简单的打开页面功能，OneActivity 中点击按钮打开 TwoActivity 页面：

• activity_one.xml

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/main"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".OneActivity"><Buttonandroid:id="@+id/button"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="40dp"android:text="跳转TwoActivity"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toTopOf="parent"/><TextViewandroid:id="@+id/textView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="20dp"android:padding="15dp"android:text="这里是SDK的OneActivity"android:textSize="16sp"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toBottomOf="@id/button"/></androidx.constraintlayout.widget.ConstraintLayout>

• activity_two.xml

<?xml version="1.0" encoding="utf-8"?><androidx.constraintlayout.widget.ConstraintLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:id="@+id/main"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".TwoActivity"><TextViewandroid:id="@+id/textView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_marginTop="40dp"android:padding="15dp"android:textSize="16sp"android:text="这里是SDK的TwoActivity"app:layout_constraintLeft_toLeftOf="parent"app:layout_constraintRight_toRightOf="parent"app:layout_constraintTop_toTopOf="parent"/></androidx.constraintlayout.widget.ConstraintLayout>

• OneActivity.java

packagecom.example.mylibrary;importandroid.content.Intent;importandroid.os.Bundle;importandroid.view.View;importandroid.widget.Button;importandroid.widget.TextView;importandroid.widget.Toast;importandroidx.activity.EdgeToEdge;importandroidx.appcompat.app.AppCompatActivity;importandroidx.core.graphics.Insets;importandroidx.core.view.ViewCompat;importandroidx.core.view.WindowInsetsCompat;publicclassOneActivityextendsAppCompatActivityimplementsView.OnClickListener{privateButtonmButton;privateTextViewmTextView;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);EdgeToEdge.enable(this);setContentView(R.layout.activity_one);ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main),(v,insets)->{InsetssystemBars =insets.getInsets(WindowInsetsCompat.Type.systemBars());v.setPadding(systemBars.left,systemBars.top,systemBars.right,systemBars.bottom);returninsets;});initView();}privatevoidinitView(){mButton =findViewById(R.id.button);mButton.setOnClickListener(this);mTextView =findViewById(R.id.textView);mTextView.setOnClickListener(this);}@OverridepublicvoidonClick(Viewview){intid =view.getId();if(id ==R.id.button){startActivity(newIntent(this,TwoActivity.class));}elseif(id ==R.id.textView){Toast.makeText(this,mTextView.getText(),Toast.LENGTH_SHORT).show();}}}

• TwoActivity.java

packagecom.example.mylibrary;importandroid.os.Bundle;importandroid.view.View;importandroid.widget.TextView;importandroid.widget.Toast;importandroidx.activity.EdgeToEdge;importandroidx.appcompat.app.AppCompatActivity;importandroidx.core.graphics.Insets;importandroidx.core.view.ViewCompat;importandroidx.core.view.WindowInsetsCompat;publicclassTwoActivityextendsAppCompatActivityimplementsView.OnClickListener{privateTextViewmTextView;@OverrideprotectedvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);EdgeToEdge.enable(this);setContentView(R.layout.activity_two);ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main),(v,insets)->{InsetssystemBars =insets.getInsets(WindowInsetsCompat.Type.systemBars());v.setPadding(systemBars.left,systemBars.top,systemBars.right,systemBars.bottom);returninsets;});initView();}publicvoidinitView(){mTextView =findViewById(R.id.textView);mTextView.setOnClickListener(this);}@OverridepublicvoidonClick(Viewview){intid =view.getId();if(id ==R.id.textView){Toast.makeText(this,mTextView.getText(),Toast.LENGTH_SHORT).show();}}}

如果不想打包，可以在app\build.gradle直接引入模块：

dependencies {implementation project(':mylibrary')}

如下图所示：
