灵活更新和即时更新之间的区别是:
在灵活更新中,如果用户决定更新,它可以在下载期间使用应用程序,并且当下载完成时,您需要显示某些UI来调用completeUpdate()。
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == APP_UPDATE_REQ_CODE) {
if (resultCode == RESULT_CANCELED) {
// App update is canceled by the user so re-open the in-app update screen.
// This block of code is executed if user clicks cancel button from the in-app update screen or press the hardware back button.
checkForAppUpdate();
} else if (resultCode == RESULT_OK) {
// App successfully updated to the latest version.
finish();
} else {
// Update fails then re-open the in-app update screen.
checkForAppUpdate();
}
}
}
private void checkForAppUpdate(){
if (this instanceof SplashActivity){
return;
}
if (appUpdateManager == null){
appUpdateManager = AppUpdateManagerFactory.create(this);
}
Task<AppUpdateInfo> appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();
appUpdateInfoTask.addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
&& appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
startUpdateFlow(appUpdateInfo);
}
});
