Whole application hangs after adding this software

[GeraldR63]

Hello,

it crashes my whole application. Changes made until now:

------------------------------build.gradle (Module: ) Begin snippet dependencies {

implementation 'androidx.appcompat:appcompat:1.5.1'
implementation 'com.google.android.material:material:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
implementation 'androidx.navigation:navigation-fragment:2.5.3'
implementation 'androidx.navigation:navigation-ui:2.5.3'
**implementation 'com.github.mhiew:android-pdf-viewer:3.2.0-beta.1'**
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.5'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'

} ------------------------------build.gradle (Module: ) End snippet

------------------------------gradle.properties (Project Properties ) Begin snippet added lines at end of file maven {url "https://jcenter.bintray.com"} android.enableJetifier=true ------------------------------gradle.properties (Project Properties ) Begin snippet

Added to my Java Code to manage the fragment:

import com.github.barteksc.pdfviewer.PDFView; import com.github.barteksc.pdfviewer.listener.OnLoadCompleteListener; import com.github.barteksc.pdfviewer.listener.OnPageChangeListener; import com.github.barteksc.pdfviewer.listener.OnPageErrorListener; import com.github.barteksc.pdfviewer.scroll.DefaultScrollHandle; import com.github.barteksc.pdfviewer.util.FitPolicy; import com.shockwave.pdfium.PdfDocument;

Remark: The akronym "github" is marked red.

Inside the class I added:

PDFView pdfView;

So far I see it hangs at:

public void onViewCreated(@NonNull View view, Bundle savedInstanceState)

{
   super.onViewCreated(view, savedInstanceState);

** pdfView=view.findViewById(R.id.dfDocumentation); ** }

No chance to debug this stuff.

Anyone any suggestions and help?

regards Gerald
