请尝试一次。 Official Document for reference
第一步：在 build.gradle 文件中添加以下库（请检查并更新最新的播放代码插件版本）
implementation 'com.google.android.play:core:1.6.4'
第 2 步：在类中声明以下变量（例如 MainActivity.java）
private AppUpdateManager mAppUpdateManager;
private int RC_APP_UPDATE = 999;
private int inAppUpdateType;
private com.google.android.play.core.tasks.Task<AppUpdateInfo> appUpdateInfoTask;
private InstallStateUpdatedListener installStateUpdatedListener;
第 3 步：在 onCreate() 方法中添加以下代码（初始化变量）
// Creates instance of the manager.
mAppUpdateManager = AppUpdateManagerFactory.create(this);
// Returns an intent object that you use to check for an update.
appUpdateInfoTask = mAppUpdateManager.getAppUpdateInfo();
//lambda operation used for below listener
//For flexible update
installStateUpdatedListener = installState -> {
if (installState.installStatus() == InstallStatus.DOWNLOADED) {
popupSnackbarForCompleteUpdate();
}
};
mAppUpdateManager.registerListener(installStateUpdatedListener);
第 4 步：在活动的 onDestroy() 方法中取消注册监听器
@Override
protected void onDestroy() {
mAppUpdateManager.unregisterListener(installStateUpdatedListener);
super.onDestroy();
}
第 5 步：在 onResume() 中，我们需要通过以下代码监听灵活和即时更新。
@Override
protected void onResume() {
try {
mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() ==
UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
// If an in-app update is already running, resume the update.
try {
mAppUpdateManager.startUpdateFlowForResult(
appUpdateInfo,
inAppUpdateType,
this,
RC_APP_UPDATE);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
});
mAppUpdateManager.getAppUpdateInfo().addOnSuccessListener(appUpdateInfo -> {
//For flexible update
if (appUpdateInfo.installStatus() == InstallStatus.DOWNLOADED) {
popupSnackbarForCompleteUpdate();
}
});
} catch (Exception e) {
e.printStackTrace();
}
super.onResume();
}
第6步：在onActivityResult()中我们需要处理用户点击动作（仅用于灵活更新）
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_APP_UPDATE) {
//when user clicks update button
if (resultCode == RESULT_OK) {
Toast.makeText(MainActivity.this, "App download starts...", Toast.LENGTH_LONG).show();
} else if (resultCode != RESULT_CANCELED) {
//if you want to request the update again just call checkUpdate()
Toast.makeText(MainActivity.this, "App download canceled.", Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_IN_APP_UPDATE_FAILED) {
Toast.makeText(MainActivity.this, "App download failed.", Toast.LENGTH_LONG).show();
}
}
}
第 7 步：创建一个方法来检查更新是否可用并开始更新（立即更新）
private void inAppUpdate() {
try {
// Checks that the platform will allow the specified type of update.
appUpdateInfoTask.addOnSuccessListener(new OnSuccessListener<AppUpdateInfo>() {
@Override
public void onSuccess(AppUpdateInfo appUpdateInfo) {
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
// For a flexible update, use AppUpdateType.FLEXIBLE
&& appUpdateInfo.isUpdateTypeAllowed(inAppUpdateType)) {
// Request the update.
try {
mAppUpdateManager.startUpdateFlowForResult(
// Pass the intent that is returned by 'getAppUpdateInfo()'.
appUpdateInfo,
// Or 'AppUpdateType.FLEXIBLE' for flexible updates.
inAppUpdateType,
// The current activity making the update request.
MainActivity.this,
// Include a request code to later monitor this update request.
RC_APP_UPDATE);
} catch (IntentSender.SendIntentException ignored) {
}
}
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
第 8 步：精细地创建一个小吃对话框或任何警报，以向用户显示灵活更新已下载并准备好更新（需要使用操作来开始更新 - 仅用于灵活更新）
private void popupSnackbarForCompleteUpdate() {
try {
Snackbar snackbar =
Snackbar.make(
findViewById(R.id.id_of_root_loyout),
"An update has just been downloaded.\nRestart to update",
Snackbar.LENGTH_INDEFINITE);
snackbar.setAction("INSTALL", view -> {
if (mAppUpdateManager != null){
mAppUpdateManager.completeUpdate();
}
});
snackbar.setActionTextColor(getResources().getColor(R.color.install_color));
snackbar.show();
} catch (Resources.NotFoundException e) {
e.printStackTrace();
}
}
第 9 步：现在调用具有应用内更新类型（灵活或即时）的方法，无论您想开始检查更新。
//For Immediate
inAppUpdateType = AppUpdateType.IMMEDIATE; //1
inAppUpdate();
//For Flexible
inAppUpdateType = AppUpdateType.FLEXIBLE; //0
inAppUpdate();
要记住的要点：
-
灵活的更新将首先下载，然后它会通知用户下载完成，然后用户必须开始更新（上面第 8 步给出的选项）。
-
google play 控制台有一个测试应用内共享的选项，我们可以上传普通的apk（不需要签名的apk）来测试。

-
需要在您的测试设备 Play 商店应用中启用应用内共享选项。

-
不过，Play 商店中的任何问题，只需清除缓存并清除数据，然后重新启动设备并尝试。
