targetSdkVersion setting

Question

If someone could help me with this. I downloaded AndroidSDK and everything else needed for android programming, and I faced some problems with (funny to say) hello world.

I just do not get the thing with tarketSdkVersion setting in AppManifest. Whenever it is not set to "13" (just noticed 8 which is my minSdkVersion is working also) application has "Unfortunately application stopped working" screen with this in LogCat:

I do not get if this is intentional, I got some SDK errors or something else. I was googling for answers but coulnt find any. Tell me if I should add some more info from project, looking for your answers.

EDIT: Forgot to add, I got an android device with 4.4.2 KitKat so I wanted to make project target set to 20. That is how I noticed this errors.

EDIT2:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="pl.bbZoftware.eclipsestandalone.MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/hello_world" />

</RelativeLayout>

EDIT3:

manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="pl.bbZoftware.eclipsestandalone"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="13" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 1

Most probably you are making mistake on activity_main.xml

Also target for 4.4.2 Kitkat is 19. Have a check in this android api levels page.

Answer 2

Just remove android:targetSdkVersion from AndroidManifest.xml

Make following changes: From

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

To:

<uses-sdk android:minSdkVersion="8" />

Answer 3

ChangetargetSdkVersion in [project directory]\app\build.gradle to something less than or equal to 19. Change:

defaultConfig {
    applicationId '....'
    minSdkVersion 8
    targetSdkVersion 21
}

To:

defaultConfig {
    applicationId '....'
    targetSdkVersion 19
}

Answer 4

Android API 20 gives compilation issues. Make sure to be using the API 19 and set it as a Targeted SDK during development.

Answer 5

I just found where the problem was.

Do not use API Level of 20 and Platform 4.4W, as Android Virtual Device. With Level 19 and Platform 4.2.2 set on ADV everything runs as it should.
