Using <uses-library> in AndroidManifest file only for specific devices - java

I have Android application, that will work on the different devices with scanners. And for one device model I need to use their SDK, which requires to add next code into AndroidManifest file.
<uses-library
android:name="com.datalogic.device"
android:required="true" />
The problem is in that, if I will try to run this application on the another device model, program will not compile. Getting next
error. When I'm removing code, which I included above, from Manifest file, everything works good.
So is that possible to write in Java code or in the AndroidManifest file, something that will check device name, and will decide to use uses-library code or not?

You can check the device model by getting the string value of android.os.Build.MODEL;, you will get the model number (ex : SM-G928F for Galaxy S6 Edge Plus) and then decide how library to use, but you can't change the manifest at runtime

Action requested: Declare your Ad ID permission

Today i have got this email:
Last July, we announced Advertising policy changes to help bolster
security and privacy. We added new restrictions on identifiers used by
apps that target children. When users choose to delete their
advertising ID in order to opt out of personalization advertising,
developers will receive a string of zeros instead of the identifier if
they attempt to access the identifier. This behavior will extend to
phones, tablets, and Android TV starting April 1, 2022. We also
announced that you need to declare an AD_ID permission when you update
your app targeting API level to 31 (Android 12). Today, we are sharing
that we will give developers more time to ease the transition. We will
require this permission declaration when your apps are able to target
Android 13 instead of starting with Android 12.
Action Items If you use an advertising ID, you must declare the AD_ID
Permission when your app targets Android 13 or above. Apps that don’t
declare the permission will get a string of zeros. Note: You’ll be
able to target Android 13 later this year. If your app uses an SDK
that has declared the Ad ID permission, it will acquire the permission
declaration through manifest merge. If your app’s target audience
includes children, you must not transmit Android Advertising ID (AAID)
from children or users of unknown age.
My app is not using the Advertising ID. Should i declare the AD_ID Permission in Manifest or not?
Case 1: The app doesn't contain any Ads:
You can simply remove/ignore it by adding tools:node="remove" in the AndroidManifest.xml file.
<uses-permission android:name="com.google.android.gms.permission.AD_ID" tools:node="remove"/>
Make sure you have xmlns:tools at the top of AndroidManifest.xml file
Even if another third-party library asks for this specific permission, the build will be forced not to merge it in your final Manifest file.
You can get more info from this SO answer.
Case 2: The app contains Ads:
Add the following to AndroidManifest.xml before </manifest>:
<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
You can get more information from here.
If your app uses the Google Mobile Ads SDK(Admob) version 20.4.0 or higher, you can skip setting up the permission manually since the SDK automatically declares it
More informations here:
https://developers.google.com/admob/android/quick-start
Case 1: Your App has Ads
Add the following to AndroidManifest.xml before </manifest>:
<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
Case 2: Your App Doesn't have Ads
At the top of your AndroidManifest.xml make sure you have xmlns:tools on the <manifest ...>. (kudos to this answer) e.g.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.mycompany.myapp">
Then, add the following at the bottom of the page, before </manifest> tag:
<uses-permission android:name="com.google.android.gms.permission.AD_ID" tools:node="remove"/>

Google's Doc: https://developers.google.com/android/reference/com/google/android/gms/ads/identifier/AdvertisingIdClient.Info#public-methods
Google describe here how to solve
https://support.google.com/googleplay/android-developer/answer/6048248?hl=en
Add in manifest
<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
If your app doesn't contain ads, make sure you complete the survey on App content page (Policy > App content) in Play Console.
Just select the option: No, my app does not contain ads.
If you don't do that, you won't be able to upload new releases of your app to Google Play.
First of all,
com.google.android.gms.permission.AD_ID can be added by other third party SDK like
Play Services-ads
firebase-analytics etc
So, if you haven't added permission.AD_ID manually, make sure it is not added by any other SDK by checking merged manifest file.
merged-manifest path:
project > app > build > intermediate > merged_manifest > release > AndroidManifest.xml
Now go to your play console > app content > Adverstising ID and
Select NO if your merged manifest doesn't contain AD_ID, else
Select YES and complete next option.
In my case, I used Firebase Analytics only for crash reports etc.
You can set your app to use advertising ID.
And use Analytics only.
Don't worry. All developer who uses Admob for advertisement received this warning. Just make sure you are using Latest Google Mobile Ads SDK(Admob) OR AdMob SDK version higher or equal to 20.4.0 in your build.gradle file. In that case SDK automatically manage it.
Otherwise for older sdk below 20.4.0, we need to manually mention below line in our AndroidManifest.xml
<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
There are two different forms:
Ads
Advertising ID
Initially, I got stuck because I did not notice the other. So your app can be in any combination, for example, no ads, but yes, advertising ID.
In this documentation it is explained that Google services can include the advertising ID for other reasons that are not ads: Analytics.
Google Play Services version 4.0 introduced new APIs and an ID for use by advertising and analytics providers. Terms for the use of this ID are below.
And in this other documentation, in the examples section is very clear that ads are understood as what is commonly understood as ads: banners, pop-ups, a tile in the middle of a list, etc.
Analyzing the merged manifest we can see that the library play-services-measurement-api is adding the permission and is related to Analytics. The library manifest looks like this:
<uses-permission android:name="com.google.android.gms.permission.AD_ID" />
<application>
<service
android:name="com.google.firebase.components.ComponentDiscoveryService"
android:exported="false" >
<meta-data
android:name="com.google.firebase.components:com.google.firebase.analytics.connector.internal.AnalyticsConnectorRegistrar"
android:value="com.google.firebase.components.ComponentRegistrar" />
</service>
</application>
Please notice that library is registering analytics.connector.internal.AnalyticsConnectorRegistrar.
In this case the Ads form must be mark with no but the Adverising ID form must be mark with yes and then the Analytics option.
I have seen people recommending force the manifest to not merge the permission.AD_ID but that would break the Analytics.
I also received today's mail from the PlayStore team to all developers. Asking to declare AD_ID permission.
Since we developed and released our application using Flutter with android targeting to API level 31. I'm using the advertising_identifier: ^0.1.1 plugin to get the advertising client ID. I haven't declared AD_ID permission in my manifest file.
Additionally, apps updating their target API level to 31 (Android 12) and using advertise identifier / advertise id client info fetch will need to declare a Google Play services normal permission in the manifest file as follows:
<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
Refered,
https://support.google.com/googleplay/android-developer/answer/6048248?hl=en
when you set targetSdkVersion 33 you must need to add the below line in the manifest file
<uses-permission android:name="com.google.android.gms.permission.AD_ID" tools:node="remove"/>
if you are not set this, show a warning on the play console when your is in production.

How to prevent Admob ad ids from leaked by android hackig app

I have developed an android app. All the things are working fine but the main problem is, using the Hack App Data anyone can see the ad codes which is a very dangerous threat.
Now how can i prevent hack app to open my application or edit my application data or how can i prevent hack app data to access this sensitive information?
note: I have turned off android:exported="false" and also add <permission android:protectionLevel="signature"
android:name="apricot.com.newshunt"/> to my menifest file
you can set the Copy Protection to On in the Android Market upload page. It's near the bottom. I doubt it is fool-proof but it can help keep some of the people likely to do this from being able to.
You should add the view in Java instead of XML and obfuscate your code.

How to turn airplanemode ON on Android programatically on API23

I'm trying to turn airplanemode on on Android but I got the following message:
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.AIRPLANE_MODE
From my point of view (and some researches):
(1) I'm using all necessary permission to do that:
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />
(2) The code is not wrong:
Settings.Global.putInt(
context.getContentResolver(),
Settings.Global.AIRPLANE_MODE_ON, 1);
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", true);
context.sendBroadcast(intent);
I know that the app needs to be installed as a system app, so I'm installing that under /system/app/my-app/ (I tried /system/priv-app/my-app/ too) and added all the permissions to the folder and to the apk.
The last thing that I tried was the include of android:sharedUserId="android.uid.system" at the AndroidManifest.xml, but doing that the application disappears.
What am I missing here, after all those attempts?
ps: The device is rooted.
Thanks in advance
It seems although Airplane Mode has become a Constant value as of API Level 17 as per the Android development documentation.
Why are you turning airplane mode on? Is there a certain functionality you are trying to accomplish?
I would've posted this in the comments, but I don't have enough rep... tfw

Shoud I Root My Android Phone to Write/Read From SD Card?

Yesterday, I tried to make some simple apps which can download xml files from website, and put them on /mnt/sdcard/ . And fortunately, I succeeded in doing it. However, just a moment ago, I wondered if it works just because my phone is rooted. So I wonder if it works on un-rooted android phones?
And thank you, I found the answer :
It will work both rooted an un-rooted phone. It wont be any problem. :)
The answer is: No, you shouldn't. Just make sure you add the Write permission in your msnifest (and I think you already did).
You should be able to read/write files to your SD card without any issues.
Android supports also access to the SD card, all files and directories
on the SD are read and writable for all applications.
This tutorial contains more information.
Not needed.
Add this line to your AndroidManifest.xml inside Manifest tag
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Using maps from Google

I'm trying to develop an application using Google's maps and I can't get this application to work. I have done all what is described in the tutorial of the "MapView" sample code, including getting a map key associated to the MD5 signature of my "debug.keystore" file but the emulator definitively says that the application has stopped unexpectedly.
This error message appears when I try to process the setContentView line of code.
The only point where I am not sure of doing what must be done is about the signature of my application : as far as I have understood the signing process of an application, in debug mode, there is nothing to do. Is it correct?
I develop in Java using the Netbeans IDE.
Thanks for the time you will spend trying to help me.
First off, I'd recommend you very much to switch to Eclipse where the official Android plugin is available which will actually give you the LogCat (that's phone-side console) and you will always know what's wrong when something doesn't work. I'm not so sure that the plugin for NetBeans works equally well.
Secondly, regarding your crash, it has nothing to do with the API Key (if the key was wrong, you would see an empty map). Two things here from the top of my mind:
the Android version you need is the
"Google APIs", not vanilla "Android"
you didn't mention that Map library in the Manifest
So make sure that the library used with your project is "Google APIs" (of desired version, I'd stick with 2.1 or 2.2) and that there's this line in the Manifest file
<application ...>
...
<uses-library android:name="com.google.android.maps" />
</application>
Other than that, would be awesome to see some stack trace to be 100% sure.
