Recyclerview inside scrollview not scrolling smoothly

RecyclerView v = (RecyclerView) findViewById(...);
v.setNestedScrollingEnabled(false);

As an alternative, you can modify your layout using the support design library. I guess your current layout is something like:

<ScrollView >
    <LinearLayout >
       <View > <!-- upper content -->
            <RecyclerView > <!-- with custom layoutmanager -->
    </LinearLayout >
</ScrollView >

Error : Library projects cannot set applicationId. applicationId is set to 'com.sample.example' in default config.

ApplicationId in Library Projects :-

You cannot use applicationId to customize the package of a library project. The package name has to be fixed in library projects (and specified as packageName in the manifest). The Gradle plugin did not enforce this restriction earlier.

Removing applicationId variable from the library's build.gradle file should resolve the issue.

Gradle Issue : Process finished with non-zero exit value 2

Click here

This issue is quite possibly due to exceeding the 65K methods dex limit imposed by Android. This problem can be solved either by cleaning the project, and removing some unused libraries and methods from dependencies in build.gradle, OR by adding multidex support.

So, If you have to keep libraries and methods, then you can enable multi dex support by declaring it in the gradle config.

defaultConfig {        
    // Enabling multidex support.
    multiDexEnabled true
}

Gradle Issue : Manifest merger failed when importing library project

It seems to be the fault of the mainfest Merger tool for gradle.

Solved it by adding to my manifest tag xmlns:tools="http://schemas.android.com/tools"

Then added tools:replace="android:icon,android:theme" to the application tag

This tells the merger to use my manifest icon and theme and not of other libraries

Example:-

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"  // add tools line here 

    package="yourpackage">

    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"

        android:supportsRtl="true"

        android:theme="@style/AppTheme"

        tools:replace="android:icon"> ///add this line 

.....

</application>

</manifest>

Hope it helps thanks

Android - RequestFeature Error

android.util.AndroidRuntimeException: requestFeature() must be called before adding content

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.mainmenu);


You should call window request before calling super.onCreate(), which is shown below,

@Override
public void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainmenu);
}

Error:- Unable to execute dex: Multiple dex files define Llombok/AccessLevel

This error will occur when there are two files in your "libs" folder.

Even I had the same issue because I had two Lombok jar files. One jar file is older version and the other one is latest version. Remove the older one(as I did) and run your project again.

This will solve the issue.

Thanks, Happy Coding.

Unable to load annotation processor factory 'compile-libs/androidannotations-2.7.1.jar' for project

Hi Friends,

I have faced this problem after checking out the project from SVN. The problem was it can't find the android annotations jar file.

You can fix this by going to Project Properties, selecting Java Compiler and expanding the Annotation Processing item. You can then remove and re-add the appropriate jar file under the Factory Path.

Once I did this, then the project built without any problems.
