i want to detail description to solve this error in my project, and why coming this.

The tool namespace needs to be explicitely declared inside your manifest header.
Add this attribute to your manifest markup :
xmlns:tools="http://schemas.android.com/tools"
As a result your header will look like :
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.Guru.Hwelth">
cf.
[Tools: replace not replacing in Android manifest

Add the tools namespace explicitly,
xmlns:tools="http://schemas.android.com/tools"
as attribute to your manifest root element

In the attached screenshot, it shows designed for phone, which means that it is supported by phone only.
Reason might be like the app does not make use of Honeycomb-specific features, which are included to support android tablets.

INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error while installing app android

I am facing the INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error when trying to install my app.
I have gone through all the solutions available for this error on stack overflow. There is no capital letter in my mainfest file package name.
Can anyone point out what might be the problem?

Your meta data is incorrect:
<meta-data android:name="android.support.multidex.MultiDexApplication" />
As stated in the api a meta-data tag is a name-value pair and needs a value or resource. It must be for example:
<meta-data android:name="android.support.multidex.MultiDexApplication"
android:value="#string/yourValue" />
or
<meta-data android:name="android.support.multidex.MultiDexApplication"
android:resource="#string/yourValue" />
Change this, delete your app from device, clean project and reinstall it.

App not supported on some devices

My app doesn't support a specific android device (Samsung Galaxy Tab 3 10.1 P5210), though it supports other 10 inch tablets. I am clueless as to why this is happening. What could be the reason?
The client has the above mentioned tablet and my app doesn't get listed on his store.

</manifest>

In your manifest you are specifying that your app requires openGL ES 2.0:
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
Hence it will run only on devices that do.
It's the only requirement besides the Android version, therefore I guess your Samsung Galaxy Tab 3 doesn't.
Besides, you might want to change your package name from com.example.app to something else.

The problem was with the Camera Permission. When I removed that permission, my client's tab began supporting the app. But I still find it strange since the tab had both front and rear camera.

Try adding back the camera permission as you need it and specify the allowed screen sizes on the manifest. I reccomend you to add this code under uses-permissions tag for example...
<supports-screens
android:anyDensity="true"
android:resizeable="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true"
android:xlargeScreens="true"
android:largestWidthLimitDp="2560"
android:compatibleWidthLimitDp="2560" />
Hope it helps!
