java无法使用Play Core库提供的inapp更新支持更新应用程序
我只是想实现GooglePlayCoreLibraryAPI提供的应用内更新服务
在将更新版本的应用程序发布到内部测试轨道后，我在play store中获得更新版本的应用程序
但是，我无法在同一页上看到“更新”按钮
此外，应用程序被禁用，以根据代码的实现进行更新。 请帮我解决这个问题
private AppUpdateManager appUpdateManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appUpdateManager = AppUpdateManagerFactory.create(this);
InAppUpdate.setImmediateUpdate(appUpdateManager, this);
}
@Override
protected void onResume() {
super.onResume();
InAppUpdate.setImmediateUpdateOnResume(appUpdateManager, this);
}
}
及
public class InAppUpdate {
public static int REQUEST_APP_UPDATE = 302;
public static void setImmediateUpdate(AppUpdateManager appUpdateManager, Activity activity) {
appUpdateManager
.getAppUpdateInfo()
.addOnSuccessListener(
appUpdateInfo -> {
// Checks that the platform will allow the specified type of update.
if ((appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE)
&& appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.IMMEDIATE)) {
// Request the update.
try {
appUpdateManager.startUpdateFlowForResult(
appUpdateInfo,
AppUpdateType.IMMEDIATE,
activity,
REQUEST_APP_UPDATE);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
});
}
public static void setImmediateUpdateOnResume(AppUpdateManager appUpdateManager, Activity activity) {
appUpdateManager
.getAppUpdateInfo()
.addOnSuccessListener(
appUpdateInfo -> {
if (appUpdateInfo.updateAvailability()
== UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
// If an in-app update is already running, resume the update.
try {
appUpdateManager.startUpdateFlowForResult(
appUpdateInfo,
AppUpdateType.IMMEDIATE,
activity,
REQUEST_APP_UPDATE);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
});
}
public static void setFlexibleUpdate(AppUpdateManager appUpdateManager, Activity activity) {
InstallStateUpdatedListener installStateUpdatedListener = installState -> {
if (installState.installStatus() == InstallStatus.DOWNLOADED) {
Snackbar snackbar =
Snackbar.make(
activity.findViewById(安卓.R.id.content),
activity.getString(R.string.in_app_snack_bar_message),
Snackbar.LENGTH_INDEFINITE);
//lambda operation used for below action
snackbar.setAction(activity.getString(R.string.in_app_snack_bar_action_title), view ->
appUpdateManager.completeUpdate());
snackbar.setActionTextColor(activity.getResources().getColor(R.color.in_app_snack_bar_text_color))
;
snackbar.show();
} else
Log.e("UPDATE", "Not downloaded yet");
};
appUpdateManager
.getAppUpdateInfo()
.addOnSuccessListener(
appUpdateInfo -> {
// Checks that the platform will allow the specified type of update.
if ((appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE)
&& appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.FLEXIBLE)) {

try {

AppUpdateType.FLEXIBLE,

REQUEST_APP_UPDATE);
} catch (IntentSender.SendIntentException e) {

appUpdateManager.registerListener(installStateUpdatedListener);

问题可能是您正在使用的应用程序是通过USB电缆安装的，而不是从PlayStore安装的。从playstore安装你的应用程序，然后它就可以工作了。另外请注意，当使用应用程序内更新时，应用程序的缓存可能会阻止它识别新上载的更新，因此请重新启动应用程序几次，如有必要，请删除缓存以强制它从google play重新加载数据
