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

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

</manifest>

1、上面是设置主窗体；

2、调用其他窗体

@SuppressLint("ShowToast")
public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
    }


    @Override
    protected void onNewIntent(Intent intent) {
        //super.onNewIntent(intent);
        init();
    }

    public void  init(){

        startActivity(new Intent(getApplicationContext(),LoginActivity.class));
    }

}

 3、Gradle.builde  这个好像还不怎么清楚；

// 声明是Android程序
apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.wbh.hoge.crmapp"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    //移除lint检查的error
    lintOptions {
        abortOnError false
    }
    buildTypes {
        release {
            // 是否进行混淆
            minifyEnabled false
            // 混淆文件的位置
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    // 编译libs目录下的所有jar包
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:support-v4:23.1.1'
    compile 'com.umeng:fb:5.4.0'
    compile 'com.jiechic.library:xUtils:2.6.14'
}
repositories {
    jcenter()
    maven { url "https://raw.githubusercontent.com/umeng/mvn-repo-umeng/master/repository" }
}
