I wrote a webview application for some Android 4.2 device with a custom inapp keyboard. In fact, the app runs without any error on devices with Android 4.2.
I know this is a very old android version, this is reason why I got now a new device with Android 7.1.2, but unfortunately, the app doesn't work on this device.
In the following code example I create an InputConnection to the WebView and assume that reference to my custom keyboard.
This is the code who turns into an error:
val ic = mWebView.onCreateInputConnection(EditorInfo())
mMyKeyboard.setInputConnection(ic)
Code of "setInputConnection" of object "MyKeyboard"
fun setInputConnection(ic: InputConnection) {
inputConnection = ic
}
error message:

Currently I have no idea why this happens.
The documentation for "onCreateInputConnection" of WebView object show it should be fine.
Android Developers | Webview
There is no different if I compile it under API 19 (Android 4.2) or API 25 (7.1).
Does anyone have any idea what the problems might be?
Thanks in advance
It seems like I found the problem.
In the app for Android 4.2 the above code of getting and assuming the inputConnection was part of the "onCreate" function. It semms like Android 7.1 works there a little bit different, after I moved the specified code part to "onPageFinished" function, it works fine.
I guess there is a reference missing in the onCreate function. But I find it odd that it worked before.

When I run my app on the emulator with version 27 & 28 APIs, everything works for me. However, as soon as I try to go to a lower level API, I get error messages regarding the setContentView() method in my custom Activity.java class.
Here is the stack trace:

I tried to run this app on both a phone and emulator with a version 24 api, and nothing works. My activity_main.xml that the onCreate() method tries to call just contains two fragments that are modified in the onCreate() method. Here is a snippet of code from that:
/* This code runs perfectly fine on the version 28 and 27 api on the emulator*/
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
images = new ArrayList<>();
imageNames = new ArrayList<>();
setContentView(R.layout.activity_main);
Log.v(TAG, "I got in onCreate");
//Create the fragment for the ranking and add it to the current view
// Get references to the TitleFragment and to the QuotesFragment containers
mRibbonFrameLayout = findViewById(R.id.ribbon_fragment_container);
mChecklistFrameLayout = findViewById(R.id.checkbox_fragment_container);
...
}
I tried looking this problem up, but nothing I found has solved this problem - at least publicly.
UPDATE Solved within 5 minutes when I figured out that a folder had a version of 26, which would limit on using that version.
This question already has answers here:
What is a NullPointerException, and how do I fix it?

Closed 5 years ago.
I'm developing an Android application with Android Studio and since today I can no longer run the app because when Android Studio installs the apk on my device, the package installer crashes with the following message "Unfortunately, package installer has stopped". The strange thing is that when I run the application I can see for a second the main activity and its components but then everything crashes.
This is the exception:

Thank you very much in advance
You have an issue with "granted permissions on runtime", basically you must grant permissions to use specific functionalities.
Have a look here: https://developer.android.com/training/permis
Have a look at you manifest and check which of the "user-permissions" are required to check in runtime, if you have not user-permissions added, then now is the time https://developer.android.com/guide/topics/manifest/uses-permission-element.html.
Then use the code provided in the first link after to check runtime permissions.
Remember: ask permissions on runtime is required for Android 6.0 (API level 23) and above. On lower SDK (<=22), is enough adding the "user-permissions" into the manifest.
I am getting error while opening scanning bar code on the below line of code:
static
{
System.loadLibrary("iconv");
}
After that getting run time exception as mentioned below:

Please help me on this.
i'm not using ZBAR but i work on project Reading barcode

Check this Link
Please try this:
Download the latest ZBar project here
grab the latest .so from barcodescanner/zbar/src/main/jniLibs, and replace the relative .so in your project.
Run your app.
(Works well targetSdkVersion 25, buildToolsVersion '25.0.3', compileSdkVersion 25, or below)
I have just updated the OS on my phone to Android 5.0.1. Since this update, an app that I am working on, that is working perfectly fine on my other devices, is now throwing an error in 5.0.1 only. I have no idea what this error means, and it isn't pointing me to a suspicious line of code like it often does.
Has anyone seen this or know what it is about with the new 5.0.1?

For anyone else having any issues since the Android update, I have found and resolved my issue.
The allowed maximum method size has obviously changed. Some of my methods were quite large and complex, and this new limit was obviously exceeded.
This fix was to break larger sections of code into smaller sections.
Hope this helps someone.
I'm trying to integrate MonkeyTalk automation into my pre-existing Android app that is built using gradle.
I followed the steps here: Android Studio and MonkeyTalk? and got the demo app working, but when I run it in my own application I get the following crash on the second screen. Any idea why this happens?
This particular stack trace is using L preview targeting SDK 19, but I've also seen a similar (less detailed) stack trace on a Galaxy S4 with SDK 18 on it.

You can try the latest version of the monkeytalk and i guess your problem will not occur again.
