When working with any Android project, it is common to experience some error messages. The error message includes activity not found exception, class cast exception, error converting a byte to dex, null pointer exception, and many more. These messages are typically encrypted and short. At first glance, you may not understand what the error messages actually are before you can solve Android’s most common error messages.
Typically, these messages contain all the information you require to resurrect your project. You will just need to know how to decrypt these error messages. However, we will let you know some common error messages you are most likely to experience when developing Android applications and possible troubleshooting.
What Are Actually Error Messages In Android?
Whenever you go to develop an Android app, you are likely to get some error messages. Android will actually display error messages according to the type of error you encountered. For example, if your Android Studio has any errors in XML files, you will get an “Android resource linking failed” error.
Such errors displayed in Android Studio will be difficult to understand because the Logcat monitor contains a lot of information. Don’t worry; we will help you understand the different error messages with the possible solution in the section below.
10 Ways to Solve Android’s Most Common Error Messages
Troubleshooting is a critical part of Android development. It allows you to fix all the errors, bugs, and performance issues of an Android app. Some common Android error messages and possible solutions are demonstrated below for your convenience.
When developing any Android app, Java enables you to cast one variable over another. This will function until casting occurs within compatible data types.
The ClassCastException error indicates that you tried to attribute an object into a subclass. For example, trying to propel a string at an integer. To fix this issue, open the section of your code that indicates the error message and examine what objects are being cast here.
ActivityNotFoundException error happens when a call to start activity fails. Basically, this error happens when the activity will not found. To solve this error, you have to employ the activity in your manifest.
3. Resource Linking Failed
While working with Android Studio to develop apps, Android resource linking failure is one of the most common errors. This error actually happens when Android Studio gets some errors in XML files.
To resolve this error, you have to navigate and examine every XML file. When you disclose the XML files, Android Studio will identify errors automatically. This will be easy for you to resolve the errors.
This error usually occurs when you try to install your project on a physical Android or Virtual Device that doesn’t have sufficient storage. If you are using Android Device Manager, check out the steps below:
- Restart the Android Device Manager and click on the ‘Edit’ icon.
- Press on the Show Advanced Settings from the newly appeared window.
- Now scroll to the ‘Memory and Storage’ segment and enhance the memory space in your AVD.
For a physical Android Device, clean some files to free up some memory. In that case, you can delete some large media files or uninstall applications.
NullPointerException error appears when referencing an object that indicates no location in memory. For example, trying to call the instance of a null object or change the null’s slots as if it’s an array.
When the application tries to use it where an object is needed, causing the NullPointerException error. To fix this error, you will need to identify the values causing the exception. After that, set the values to the perfect locations.
6. R.layout.main Cannot Be Found
Several reasons can cause this error. You can easily solve this problem by following a simple, quick step. The simple step is clean and builds your project again.
In some cases, you may need to repeat this process several times before the R.layout.main Cannot Be Found error message stops showing. If this solution doesn’t work, you have to ensure all layout files are correctly referenced throughout your project.
If the problem appears after moving some files, you may have to clear your Android Studio’s cache files.
This error occurs when your application makes memory requests that the system can’t meet. OutofMemoryError can be caused for several reasons, but some common causes are holding onto references too long, loading large bitmaps, and memory leaks.
So, you will have to find the actual problem before fixing the error. For example, if the error is due to memory-hogging bitmaps, you need to reduce the bitmap scale. Besides, Android Studio has different tools to analyze an app so that you can find information, like memory monitor, allocation tracker, etc.
When your app tries to perform networking operations on its main thread and tends to block the thread, the error usually occurs.
To resolve the NetworkOnMainThreadException error, you have to move your internet-related code to a separate thread. Besides, you can use IntentService or AsyncTaks to wrap your network operations in a worker thread to troubleshoot this error.
9. Too many Field References
This error message will appear when your app development project contains more than 65536 references. This is because a single dex byte code file can invoke too many references.
To fix this problem, you have two simple choices. You can either reduce the number of references in your project or configure the app to use more than one dex file.
10. Please Choose a Valid Directory
When your Android Studio cannot find the JDK file on your development machine, you can experience this error. To resolve this error, check out the steps below:
- Click on File from the top-left corner of the Android Studio toolbar.
- Then select project structure and click SDK Location from the left-hand menu.
- Ensure the Use embedded JDK checkbox is checked.
If the above process doesn’t solve the error, navigate back to File and then Project Structure. After that, select SDK Location and place the entire file path for your JDK manually. If you don’t know your JDK path, ‘common /usr/libexec/java_home’ in your device’s Command Prompt or Terminal.
