I made a simple app using Cards in Material Components in Android. When I try to run it in my "OnePlus AC2001" mobile, I'm getting this error in logcat.
2021-01-31 17:28:59.544 26933-26933/? E/rialdesigncard: Unknown bits set in runtime_flags: 0x28000
But I'm not getting any error when I run the app in the emulator.
This is my MainActivity.java file:
public class MainActivity extends AppCompatActivity {
CardView cardView;
TextView textView;
CheckBox checkBox;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
cardView = findViewById(R.id.my_card_ui);
textView = findViewById(R.id.title_text);
checkBox = findViewById(R.id.checkbox);
cardView.setOnClickListener(v -> {
checkBox.setChecked(checkBox.isChecked()? false: true);
textView.setText("First title");
});
}
}
This is my ActivityMain.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

</LinearLayout>
I couldn't find the solution to this error anywhere. Please help me solve this.
I have been consistently seeing this error for some time now (OnePlus device), but I haven't been able to find a solution either. The error does not seem to impact the app in any way though.
Additional point of information:
I have observed that this error appears in the Logcat whenever I Run/Debug the app on a real device, but it does not show up consistently in the Run/Debug consoles. I haven't tried to check (as you have) if the error is replicated when using an emulator.
Also, my Logcat shows the Unknown bits set in runtime_flags: 0x20000 error for many other packages as the device is running. Some examples: .android.dialer, oneplus.weather, twitter.android, and so on.
This is what I've found out so far:
From the ARM DS5 DUI0446U Debugger User Guide, a possible memory map for internal RAM can be between 0x8000 and 0x28000. I'm not from a computer engineering background, and I'm not sure if this is a relevant direction for understanding the problem further. Searching the Android Runtime (ART) site (this, or in general, this) yielded no useful results.
For a related error, by following this answer to the ART source code, 0x28000 seems to be related to either the DEBUG_IGNORE_APP_SIGNAL_HANDLER flag or the DISABLE_TEST_API_ENFORCEMENT_POLICY flag (line 154-155 as of this time of this post). [E.g., 1 << 17 is 0x20000]
I don't have a deeper understanding of the either of the two flags. Nevertheless, the 0x20000 error seems to be pretty commonplace in production apps. While this is not an indication that the 0x28000 error is equally hassle-free, to my mind it does shed some light on the nature of the runtime_flags.
It just might be the case that errors related to these flags (see the enum in the source code) may not really "break" the app. Some further information is required in order to be absolutely certain, but the above might be good enough to not be concerned about the app breaking.
P.S.: If you think this response is good enough, do mark it as an answer so I will have some feedback as well.

I am doing a java to c# transition, and need help.
in Visual Studio 2019 Pro, Android 9.0 (Pie), I am doing this example:
https://learn.microsoft.com/en-us/xamarin/android/platform/binding-java-library/binding-a-jar
The goal is later to convert my java libs to c# for my big project.
I follow the instructions to the letter, and when I come to the part where I need to create an ImageView, there is the problem. Once I create the ImageView, it has an android:src field, something like this (auto generated):
android:src="#drawable/icon"
The problem here, is when I remove that field, in the VS designer, the ImageView disappears and it does not matter if I have the c# code or not, even when I set the srec to:""
Bellow is literally all the code in MainActivity:
using Android.App;
using Android.OS;
using Android.Support.V7.App;
using Android.Runtime;
using Android.Widget;
using Com.Squareup.Picasso;
namespace App3
{
[Activity(Label = "#string/app_name", Theme = "#style/AppTheme", MainLauncher = true)]
public class MainActivity : AppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.activity_main);
/***********************************************************************/
/**Picasso Code**/
ImageView imageView = FindViewById<ImageView>(Resource.Id.imageView1);
// Use the Picasso jar library to load and display this image:
Picasso.With(this)
.Load("http://i.imgur.com/DvpvklR.jpg")
.Into(imageView);
/**End Ff Picasso Code**/
/***********************************************************************/
}
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
{
Xamarin.Essentials.Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);
base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
}
XML Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="25px"
android:minHeight="25px">
<ImageView
android:src="#drawable/icon" <!-- this line -->
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/imageView1" />
</LinearLayout>
The app does nothing, and in the emulator, the ImageView is empty.
And there is no error, or anything.
If you need anything more, please let me know.
I hope you can help me, if not, thank you for your time.
Edit 1:
It seems, the problem lies in the C# code.
If I add the android:src field, it still does not show up on the emulator, but when I remove the code (the Picasso code) than the image(drawable/icon) shows. Still no error!!
try this
<ImageView
android:src="#drawable/icon" <!-- this line -->
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minWidth="50px"
android:minHeight="50px"
android:id="#+id/imageView1" />
This Question seems like it's been answered but not updated, I am working on Android Studios 1.5.1.0 and I am getting an error in the activity_main.xml and also in the MainActivity.java. When making my app I had no problems until i tried to run it.
This is what came up when I tried to run it
Error:(13, 24) No resource found that matches the given name (at 'theme' with value '#style/AppTheme.AppBarOverlay').
Error:(20, 29) No resource found that matches the given name (at 'popupTheme' with value '#style/AppTheme.PopupOverlay').

and in my mainactivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText tickets = (EditText)findViewById(R.id.txtTickets);
final Spinner group = (Spinner)findViewById(R.id.txtGroup);
Button cost = (Button)findViewById(R.id.btncost);
cost.setOnClickListener(new View.OnClickListener() {
final TextView result = ((TextView)findViewById(R.id.txtResult);
#Override
public void onClick(View v) {
numberOfTickets = Integer.parseInt(tickets.getText().toString());
totalCost = costPerTickets * numberOfTickets;
DecimalFormat currency = new DecimalFormat("$###,###.##");
groupchoice = group.getSelectedItem().toString();
result.setText("Cost for " + groupchoice + " is " + currency.format(totalCost));
}
});
}
All (R.) is in Red
Whenever my R is red, I've found that it's because one of my resource XML files was badly formed, such that it wouldn't compile to create the R class. Inspect recent changes to your resource files and look for problems (tag errors, wrong quotes, etc).
You must define "AppTheme.AppBarOverlay" and "AppTheme.PopupOverlay" in values/style first
clean and rebuild your project
change the version of buildTools to :
buildToolsVersion "23.0.2"
Get this setting inside the file app/build.gradle.
Did you check some of the other answers on how to update your build.gradle file?
here and here, for me worked after restart of Android Studio 2.2.2 and update.
I'm trying to add ActionBar-PushToRefresh to my project. I've followed the instructions from Chris Banes Github there: Github ActionBar-PullToRefresh
Here is my view from which I want to enable the PullToRefresh feature:
<uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ptr_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your content, here we're using a ScrollView -->
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="PULLTOREFRESH THE VIEW"
android:id="#+id/textView1" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
</ScrollView>
</uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout>
And here is my Activity to display the view:
package com.Test.pulltorefresh;
import android.app.Activity;
import android.os.Bundle;
import uk.co.senab.actionbarpulltorefresh.library.ActionBarPullToRefresh;
import uk.co.senab.actionbarpulltorefresh.library.Options;
import uk.co.senab.actionbarpulltorefresh.library.PullToRefreshLayout;
public class MainActivity extends Activity {
private PullToRefreshLayout mPullToRefreshLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Now find the PullToRefreshLayout to setup
mPullToRefreshLayout = (PullToRefreshLayout) findViewById(R.id.ptr_layout);
// Now setup the PullToRefreshLayout
ActionBarPullToRefresh.from(this)
// Mark All Children as pullable
.allChildrenArePullable()
// Set the OnRefreshListener
//.listener(this)
// Finally commit the setup to our PullToRefreshLayout
.setup(mPullToRefreshLayout);
}
}
When I launch my app, I got the blank view but nothing happens when I'm trying to PushToRefresh my view. Can someone show me how to fix it, I know that I've missed something. Thanks.
I may be a bit partial but...
you could consider using this
Maybe you have already achieved the functionality, but in the code above, you have commented out the line which defines the action on pulling the view.
//.listener(this)
You should uncomment this line and define the listener method, which should be called when the view is pulled.
The following classes could not be instantiated:
- com.amazon.device.ads.AdLayout (Open Class, Show Error Log)
See the Error Log (Window > Show View) for more details.
Tip: Use View.isInEditMode() in your custom views to skip code when shown in Eclipse

I had the same issue and followed Amazon developer guide. To solve this issue, just copy amazon library and paste it in your libs folder and than run.
It's a known issue in Eclipse ADT plugin, even if you use View.isInEditMode(), in some cases, it crashes in recent API versions (higher than 18). It's fixed in Android Studio.
If you want to see Layout Preview, you can try with different API version lower than 19.
Check the screenshot. It's using API 18. (Red box is Amazon AdLayout)
Kind of a strange issue here: Whenever I set test mode via xml, I receive the expected test ads in my emulator. However, when I try to do the same programmatically, I seem to get real ads. According to the Admob documentation, these two methods should be equivalent, no? Here is my xml code:
<com.google.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
ads:adSize="BANNER"
ads:adUnitId="xxxxxxxxxxx"
ads:loadAdOnCreate="true">
</com.google.ads.AdView>
And here is the relevant Java code:
#Override
public void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AdRequest adRequest = new AdRequest();
adRequest.addTestDevice(AdRequest.TEST_EMULATOR);
}
As mentioned before, if I insert the line ads:testDevices="TEST_EMULATOR, TEST_DEVICE_ID" into the above xml code, I get the test ad just fine. Any ideas?
I believe you have to call .loadAd(adRequest) on the AdView object.
See Google's AdMob documentation here
In the Adding a com.google.ads.AdView section.
You don't have to call it programmatically.
It took me a while until I get what device is AdMob's sdk what expecting cuz' I was thinking it was something related to the real device like ( adb devices )
But here is a comment from the official documentation that cleared it up.
"There will be a log message with the code needed to add the current device to the list of test devices"
You may get a message akin to it
I/Ads(26674): To get test ads on this device, call adRequest.addTestDevice("F1254CDFBA84BDC27F5C7C6E12445D06");
All you have to do after that is to place this ID into your layout xml as below
<com.google.ads.AdView
android:layout_alignParentBottom="true"
android:id="#+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
ads:adSize="BANNER"
ads:adUnitId="#string/publisherId"
ads:loadAdOnCreate="true"
ads:testDevices="TEST_EMULATOR, F1254CDFBA84BDC27F5C7C6E12445D06" />
Hope it helps you guys out
