在string. xml中,您可以像这样添加任何您想要的按摩。
<string name="youAreNotUpdatedTitle">Update Available</string>
<string name="youAreNotUpdatedMessage">A new version of YOUR_APP_NAME is available. Please update to version\s</string>
<string name="youAreNotUpdatedMessage1">\s now</string>
<string name="update">Update</string>
请记住,您必须在对话框代码中定义对话框的样式。
现在只需在您的基本活动中编写forceUpdate()函数并在onResume()方法中调用它,您就完成了!!
// check version on play store and force update
public void forceUpdate(){
PackageManager packageManager = this.getPackageManager();
PackageInfo packageInfo = null;
try {
packageInfo = packageManager.getPackageInfo(getPackageName(),0);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
String currentVersion = packageInfo.versionName;
new ForceUpdateAsync(currentVersion,BaseActivity.this).execute();
}
将应用程序的versionCode(您已在Playstore上发布)存储在服务器端。每次用户打开应用程序时点击API并获取versionCode。比较用户当前使用的应用程序的versionCode和您存储在服务器上的应用程序的versionCode。这是获取应用程序的versionCode的代码
PackageManager manager = this.getPackageManager();
PackageInfo info = manager.getPackageInfo(this.getPackageName(), 0);
String versionCode = info.versionCode;
如果versionCode不匹配(即来自服务器的versionCode
P. S如果您想使用此方法,您必须在每次更新Playstore上的应用程序时更新服务器上的versionCode。
