Downgrade Android SDK( api 23 -> api 21) - android

Due to some problems with permissions in SDK API 23 (Marshmallow) I wanted to switch back to API 21, yet I'm encountering some issues... I've read so many posts with similiar problems and tried (almost I guess) everything: I've updated all SDK Build/Platform Tools, features for API 21, Suport and Repository Libraries. Then I've cleaned up the project, rebuilt it and synchronized. Yet, I'm getting those errors:
My build.gradle looks like following:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.example.pablo.appcontacts"
minSdkVersion 19
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.jakewharton:butterknife:7.0.1'
compile 'com.android.support:appcompat-v7:23.1.1'
}
I'm not very familiar with this, can anybody help me to fix this cause I really can't find a way to..?

3 Steps:
1 Edit build.grade
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.stackoverflow.answer"
minSdkVersion 16
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
dependencies {
androidTestCompile 'junit:junit:4.12'
compile fileTree(dir: 'libs', include: ['*.jar'])
}
2 Sync gradle button
3 Rebuild project

Unable to add Gradle Dependency

I am trying to add this dependency to gradle, but I am receiving the below errors about other dependencies which I have not added in the first Place.
Errors :
Dependency I am trying to add is com.wdullaer:materialdatetimepicker:3.1.3
build.gradle file
apply plugin: 'com.android.application'

minSdkVersion 21

compile 'com.android.support:appcompat-v7:+'
compile 'com.wdullaer:materialdatetimepicker:3.1.3'
}
which I have not added in the first Place.
Sure you did...
Look at the source of the library you got. https://github.com/wdullaer/MaterialDateTimePicker/blob/master/library/build.gradle
compile 'com.android.support:support-v4:25.2.0'
compile 'com.android.support:support-v13:25.2.0'
compile 'com.android.support:design:25.2.0'
First, you need compileSdkVersion 25 for those to even work, then you need to allow Android Studio to "Install Repository and Sync Project" or do it yourself by updating the SDK Manager.
Change your compile and targetsdk to 25
Change your compileSdkVersion, buildToolsVersion andtargetSdkVersion
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.pf.datetimepicker"
minSdkVersion 21
targetSdkVersion 25
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:+'
compile 'com.wdullaer:materialdatetimepicker:3.1.3'
}
You have not installed the newest version of android support libraries. Just open SDK manager and install them. See the image

Emulators are not showing in Android Studio

In Android Studio the Emulators are not showing . I tried that disabling ADB Integration. but it is not working for me.
Please give me solution for this problem.
Maybe your project is not compatible (API version) with the target emulator. Check build.gradle file if the targetSDK and minimumSdk version is lower or equal to the sdk version of your Emulator.
Be sure that your compiledSdkVersion matches minSdkVersion and supported by targetSdkVersion. For example:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "24.0.0"
defaultConfig {
applicationId "zeta.sqlitetest3"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
}

Android Studio telling me it cannot resolve symbols?

Android Studio was telling me it couldn't resolve some symbols in my code. After research, it was apparent that my project was API level 23, which wasnt compatible with some of the code. I decided to change it to API level 21.
Below is the previous code in my build.gradle file
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.scriptdesigninc.test_app"
minSdkVersion 8
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.1'
}
I was told that I have to change it to the following,
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.scriptdesigninc.test_app"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
}
After I changed it, it told me I am missing the API package and that I have to download it, which I did. Then I clicked "retry" and it said it was unable to sync gradle project.
Please help, thank you in advance.
dependencies {
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}
Add the above dependency in your build.gradle file.
This is happening because Android M does not supports the Apache HTTP API

How I can change appCompat(android)

Sorry for my english. I update in compileSdkVersion 23 but my project use org.apache.http* and all is crash. I want compile in compileSdkVersion 22 what I before do. But if I change this, I have error
Error:(2) Error retrieving parent for item: No resource found that
matches the given name
'android:TextAppearance.Material.Widget.Button.Inverse'.
And I don't know how fix this. My gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
defaultConfig {
applicationId "com.home.smart.home"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile project(":slidingLibrary")
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.0'
}
but project still have this:
How I can use appCompat v22 ?
I think the problem is in the last line of your code that is
compile 'com.android.support:appcompat-v7:22.2.0'
You & I updated the appcompat to 23.0.0. I'm not able to run it as 22 but if you change it to 23 you will be able to run your project.... my build.gradle module:app file is like below & is working good
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
applicationId "com.example.inzi.app"
minSdkVersion 9
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.0'
}
set the compileSdkVersion to 23 as line 3 below & at last line, check the latest code it may help you
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.0"
defaultConfig {
applicationId "com.example.inzi.app"
minSdkVersion 9
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.0.0'
}
If you are using the support libraries v23 you have to use compileSdkVersion 23 otherwise you can have some issues like
Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse.
You can use the support libraries v22 if you want to compile with API22.
The API 23 (Android 6.0) removed the Apache HTTP client and the package org.apache.http* .
You can read more info here.
You can use the HttpURLConnection class instead or you can switch to OkHttp.

android.support.v7.internal.widget.ActionBarOverlayLayout could not be Found

I followed the all of related question for this error and i tried :
1.changing the theme of the preview activity
//but I dont need this. It just changes the preview action bar (or other something) and I dont need this. (material personal app_theme)
2.change to API-21.
//This also fixes this error but we cannot see any action bar anymore with this option.
So, my Android Studio Version is:
1.2.1.1
I'm using API-22.
Build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
defaultConfig {
applicationId "test.myapplication"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
}
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion "22.0.0"
defaultConfig {
applicationId "test.myapplication"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.0.0'
}
How to fix this?
After update the Android Studio to AI 141.1962279 From Canary Channel and i added this one on the Build.gradle and it's seems work now.
compile 'com.android.support:support-v4:22.1.1'
