由于无法在基础模块的 AndroidManifest.xml
中引用特性模块活动,因此我编写了一个 SplitInstallActivity
,它位于基础模块的 debug
源集中,并可供测试使用。 可以通过运行配置来调用它,并传递启动标志:
-e "moduleName" "feature_module" -e "className" "com.acme.feature.SomeActivity"
它通过moduleName
安装功能模块和/或通过className
启动Activity
。
在部署“默认APK”而非“应用程序包中的APK”时,这至少可以正常工作。
ArgumentKeys.java
public class ArgumentKeys {
public static final String ARGUMENT_FEATURE_MODULE_MODULE_NAME = "moduleName";
public static final String ARGUMENT_FEATURE_MODULE_CLASS_NAME = "className";
}
SplitInstallActivity.java
public class SplitInstallActivity extends AppCompatActivity implements SplitInstallStateUpdatedListener {
private static final String LOG_TAG = SplitInstallActivity.class.getSimpleName();
private SplitInstallRequest request;
private SplitInstallManager sim;
private String moduleName;
private String className;
public SplitInstallActivity() {}
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.sim = SplitInstallManagerFactory.create(this.getApplicationContext());
if(this.getIntent() != null) {
Bundle extras = this.getIntent().getExtras();
if(extras != null) {
this.moduleName = extras.getString(ArgumentKeys.ARGUMENT_FEATURE_MODULE_MODULE_NAME);
this.className = extras.getString(ArgumentKeys.ARGUMENT_FEATURE_MODULE_CLASS_NAME);
if(this.moduleName != null && this.className != null) {
this.startFeatureActivity(this.moduleName, this.className);
} else {
Log.e(LOG_TAG, "module and class are required.");
}
}
}
}
@Override
public void onStateUpdate(SplitInstallSessionState state) {
if(state.errorCode() == SplitInstallErrorCode.NO_ERROR && state.status() == SplitInstallSessionStatus.INSTALLED) {
Log.d(LOG_TAG, "dynamic feature " + this.moduleName + " had been installed.");
this.startFeatureActivity(this.moduleName, this.className);
} else {
}
}
private void startFeatureActivity(@NonNull String moduleName, @NonNull String className) {
if (this.sim.getInstalledModules().contains(moduleName)) {
Log.d(LOG_TAG, "dynamic feature module " + moduleName + " already installed.");
Intent intent = this.getIntent();
intent.setClassName(BuildConfig.APPLICATION_ID, className);
this.startActivity(intent);
this.finish();
} else {
Log.d(LOG_TAG, "dynamic feature module " + moduleName + " is not installed.");
this.installFeatureModule(moduleName);
}
}
private void installFeatureModule(@NonNull String moduleName) {
Log.d(LOG_TAG, "dynamic feature module " + moduleName + " will be installed.");
this.request = SplitInstallRequest.newBuilder().addModule(moduleName).build();
this.sim.registerListener(this);
this.sim.startInstall(this.request);
}
...
}
使用
ActivityTestRule<?>
可以自动化启动特定的
Activity
:
@Rule
public ActivityTestRule<SplitInstallActivity> mRule = new ActivityTestRule<SplitInstallActivity>(SplitInstallActivity.class) {
@Override
protected Intent getActivityIntent() {
Intent intent = new Intent();
Bundle extras = new Bundle();
extras.putString(ArgumentKeys.ARGUMENT_FEATURE_MODULE_MODULE_NAME, "feature_module");
extras.putString(ArgumentKeys.ARGUMENT_FEATURE_MODULE_CLASS_NAME, "com.acme.feature.SomeActivity");
intent.putExtras(extras);
return intent;
}
};
为了进行测试,需要在特性模块的build.gradle
中提供以下依赖项:
androidTestDebugImplementation "com.google.android.gms:play-services-basement:17.1.1"
androidTestDebugImplementation "com.google.android.play:core:1.6.4"
否则,它将无法链接测试应用程序的资源,并出现以下错误:

针对测试,还有以下选项:
AndroidManifest.xml
中时,名称空间也无法解析。 - Martin Zeitlerbundletool
,它基本上只是逐个安装所有模块。根据配置运行。这里有关于该工具的文档 https://developer.android.com/studio/command-line/bundletool - GensaGames
