使用以下代码段实现了应用内更新功能:
private void showInAppUpdateDialog(boolean isMandatoryUpdate) {
Task<AppUpdateInfo> appUpdateInfoTask = appUpdateManager.getAppUpdateInfo();
appUpdateInfoTask.addOnSuccessListener(appUpdateInfo -> {
if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE
|| appUpdateInfo.updateAvailability() == UpdateAvailability.DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS) {
int appUpdateType = isMandatoryUpdate ? IMMEDIATE : AppUpdateType.FLEXIBLE;
int requestCode = isMandatoryUpdate ? REQUEST_APP_UPDATE_IMMEDIATE : REQUEST_APP_UPDATE_FLEXIBLE;
if (appUpdateInfo.isUpdateTypeAllowed(appUpdateType)) {
// start the app update
try {
appUpdateManager.startUpdateFlowForResult(appUpdateInfo, appUpdateType, targetActivity, requestCode);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
}
}).addOnFailureListener(e -> {
e.printStackTrace();
});
}
我正在具有Android 9的设备上测试应用程序内更新。不过,它仍然给我以下错误消息(ERROR_API_NOT_AVAILABLE):
com.google.android.play.core.install.InstallException: Install Error(-3): The API is not available on this device. (https://developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE)
at com.google.android.play.core.appupdate.i.a(Unknown Source:24)
at com.google.android.play.core.internal.o.a(Unknown Source:13)
at com.google.android.play.core.internal.j.onTransact(Unknown Source:22)
at android.os.Binder.execTransact(Binder.java:731)
也就是说,请检查以下链接:https : //developer.android.com/reference/com/google/android/play/core/install/model/InstallErrorCode#ERROR_API_NOT_AVAILABLE)
使用Play核心库版本:1.6.5
最新的核心库版本:
implementation 'com.google.android.play:core:1.7.0'
但是,我不明白为什么要说ERROR_API_NOT_AVAILABLE。任何帮助,将不胜感激!
