On Android Q, that is, api 29, there may be a problem that clicking on the notification using PendingIntent cannot jump, but you can’t find the problem after searching for a long time. For example, you will encounter this problem when the app is automatically updated to be compatible with android Q. After downloading and installing, there is no problem when the app is in the foreground, but there will be problems when it is in the background, because Google prohibits background startup activities on Android Q, so when you set in gradle:
targetSdkVersion 29
Then it will appear that the system installer cannot be started when the app is in the background, so after consulting the information, someone will tell you to write like this:
app is compatible with Android Q to start the installer Compatible code:
public static void installApk(Context mContext, File apkFile) {
if (!apkFile.exists()) {
return;
}
Intent i = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_GRANT_WRITE_URI_PERMISSION); //添加这一句表示对目标应用临时授权该Uri所代表的文件
Uri apkFileUri = FileProvider.getUriForFile(mContext,
mContext.getPackageName() + ".fileprovider", apkFile);
i.setDataAndType(apkFileUri, "application/vnd.android.package-archive");
mContext.startActivity(i);
} else {
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.setDataAndType(Uri.parse("file://" + apkFile.toString()),
"application/vnd.android.package-archive");
mContext.startActivity(i);
}
}
First of all, you will find that there is no problem in writing the foreground installation like this, but there will be problems in the background installation, and then use the method of clicking the notification to start the installer to be compatible with android Q to start the activity in the background:

When there is already a notification in the foreground of the app, no more notifications will be sent, so it needs to be cleared before creating a notification
UpdateNotificationUtil notificationUtils = UpdateNotificationUtil.getInstance();
notificationUtils.clearAllNotification();
notificationUtils.sendNotificationFullScreen("新版本已下载完成", "点击安装", apkFile);
mContext.startActivity(i);
Optimized installApk method:
public static void installApk(Context mContext, File apkFile) {
if (!apkFile.exists()) {
return;
}
Intent i = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_GRANT_WRITE_URI_PERMISSION); //添加这一句表示对目标应用临时授权该Uri所代表的文件
Uri apkFileUri = FileProvider.getUriForFile(mContext,
mContext.getPackageName() + ".fileprovider", apkFile);
i.setDataAndType(apkFileUri, "application/vnd.android.package-archive");
UpdateNotificationUtil notificationUtils = UpdateNotificationUtil.getInstance();
notificationUtils.clearAllNotification();
notificationUtils.sendNotificationFullScreen("新版本已下载完成", "点击安装", apkFile);
mContext.startActivity(i);
} else {
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.setDataAndType(Uri.parse("file://" + apkFile.toString()),
"application/vnd.android.package-archive");
mContext.startActivity(i);
}
}
The Internet will tell you that writing like this is done! ! !
NO! NO! NO! In this case, there will still be problems. In this case, clicking the notification bar on some models of Huawei, oppo, and vivo will not start the installation program, but the click will not respond.
Need to add full screen notification permission
//AndroidManifest 声明新权限，不用动态申请
<uses-permission android:name="android.permission.USE_FULL_SCREEN_INTENT"/>
That's it!
