I have just build a project with android kotlin but when I run the app it got crash, and in the logcat I found this error
java.lang.NullPointerException: DataBindingUtil.setConte….layout.activity_chapter) must not be null
ChapterActivity.kt
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.databinding.DataBindingUtil
import androidx.recyclerview.widget.DividerItemDecoration
import androidx.recyclerview.widget.LinearLayoutManager
import com.tutorial.kotlinfirebasecomicreader.Common.Common
import com.tutorial.kotlinfirebasecomicreader.Model.Comic
import com.tutorial.kotlinfirebasecomicreader.databinding.ActivityChapterBinding
class ChapterActivity : AppCompatActivity() {
private lateinit var binding: ActivityChapterBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = DataBindingUtil.setContentView(this, R.layout.activity_chapter)
binding.toolbar.title = Common.selected_comic!!.Name
binding.toolbar.setNavigationIcon(R.drawable.ic_baseline_chevron_left_24)
binding.toolbar.setNavigationOnClickListener {
finish() //GO BACK
}
binding.recyclerChapter.setHasFixedSize(true)
val layoutManager = LinearLayoutManager(this#ChapterActivity)
binding.recyclerChapter.layoutManager = layoutManager
binding.recyclerChapter.addItemDecoration(DividerItemDecoration(this, layoutManager.orientation))
fetchChapter (Common.selected_comic!!)
}
private fun fetchChapter(comic: Comic) {
Common.chapterList = comic.Chapters!!
binding.txtChapterName.text = StringBuilder("Chapter (")
.append(comic.Chapters!!.size)
.append(")")
}
}
I don't really know how to fix it and I need some help

The documentation says that DataBindingUtil.setContentView returns:
The binding associated with the inflated content view or null if the layoutId is not a data binding layout.
So I would have to assume that your layout is not a valid data binding layout, so the issue lies in your XML.
I would recommend reading: Binding expressions which shows you the syntax of a valid binding layout and also this: Data Binding Library fully to help get a comprehensive understanding.
Also the answer by #Teo does point out the recommended way to use data binding so unless you have a specific reason for using the generic version I would switch to that.
Can try to avoid using DataBindingUtil as it keeps return null in my case.
You can try using its own databinding.inflate, as it will always get the correct binding.
binding = ActivityChapterBinding.inflate(layoutInflater)
setContentView(binding.root)
This might sound dumb, but in my case, this happened after renaming a package
and I forgot to clean the project, if databinding refuses to detect the new package name, according to this answer try to disable databinding in Build.gradle (Module), sync then re-enable it
And if you're using google-services, you'll need to adjust the naming part for the google-services.json as well.
I trained a tensorflow model (fully convolutional network for pixel-by-pixel image segmentation). I am trying to run it in Android studio but it always crashes. I couldn't find any solution of the issue on Stackoverflow or TF git repo.
This is what I get in Logcat:

This is the important part of Android code, where I feed the image of size 600x600 to tensorflow model and where it crashes:
Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Mat mat = new Mat();
Bitmap bmp32 = image_bitmap.copy(conf, true);
Utils.bitmapToMat(bmp32, mat);
Mat mat_resized = new Mat();
Size size = new Size(600, 600);
Imgproc.resize(mat, mat_resized, size);
Bitmap bmp_resized = Bitmap.createBitmap(600, 600, conf);
Utils.matToBitmap(mat_resized, bmp_resized);
int w = bmp_resized.getWidth();
int h = bmp_resized.getHeight();
bmp_resized.getPixels(intValues, 0, w, 0, 0, w, h);
int lenint = intValues.length;
for (int i = 0; i < intValues.length; ++i) {
final int val = intValues[i];
floatValues[i * 3 + 0] = (((val >> 16) & 0xFF) - imageMean) / imageStd;
floatValues[i * 3 + 1] = (((val >> 8) & 0xFF) - imageMean) / imageStd;
floatValues[i * 3 + 2] = ((val & 0xFF) - imageMean) / imageStd;
}
// Copy the input data into TensorFlow.
Trace.beginSection("feed");
tfHelper.feed(inputName, floatValues, 1, 600, 600, 3);
Trace.endSection();
// Run the inference call.
Trace.beginSection("run");
tfHelper.run(outputNames, logStats);
Trace.endSection();
where tfHelper is an instance of org.tensorflow.contrib.android.TensorFlowInferenceInterface.
If I comment last 3 lines, the app doesn't crash.
I think it isn't a memory issue, as I tried it also with a small version of the model (which is only ~50kB ).
Thanks!
I have an adview in one of my activitites. When I go to this activity, I get a dialog on the emulator telling me Chrome has stopped and the ad doesn't show anything.
I've checked over the code itself and I'm fairly sure it matches what it should -
Activity.xml
<com.google.android.gms.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="#string/banner_ad_unit_id"></com.google.android.gms.ads.AdView>
Activity.java
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);

On my Pixel XL, it doesn't crash, but no ad is shown, so I guess something isn't right?
We had the same crash in our app. A temporary solution was to disable the use of the preloaded_fonts tag in AndroidManifest.xml.
There appears to be a bug in Android 8.0 Oreo at present as this does not happen in earlier API's.

What is a NullPointerException, and how do I fix it?

I just finished a project in android studio and I have a problem here. When generating the application and installing on the smartphone (android nougat 7.1.1 oneplus3) it simply aborts. In the emulator it gives the message that the application stops and aborts. I need the help of you more experienced. I'm a beginner. Here's the LOGCAT lines below when you try to open the application:
