Android apps will run on API 25 only - android

This is very strange now. No matter what project it is, my android app wont run on any other roms but API 25 based only.The default hello world app even wont run on any other API.
Basically the apk installation fails on every other rom other than the ones that are nouugat based.
My minsdkversion is 21 though
Here is the build.gradle(Module:app)
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.rishav.basictest"
minSdkVersion 21
targetSdkVersion 25

})
implementation 'com.android.support:appcompat-v7:25.4.0'
testImplementation 'junit:junit:4.12'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
}
Build.gradle(Project):-
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-alpha4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

I met the same problem..
In Android Studio 2.3 and higher, There is Instant Run which may affect your code.
Disable Instant Run
File -> Settings -> Build, Execution, Deployment -> Instant Run
In my case it was working perfect,i hope may this will help you.

Failed to sync gradle project after adding Mapbox navigation SDK package.Its showing some irrelavant error [duplicate]

This question already has answers here:
Failed to resolve: com.android.support:cardview-v7:26.0.0 android
(26 answers)
Closed 5 years ago.
Here is my gradle file. I am using Appcompat 25.3.1 version, but the error is on Appcompat 26.1.0. This error goes off when navigation SDK package is removed. I dont understand what is happening. Any help is greatly appreciated.
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.example.aadhilahmed.test3"
minSdkVersion 15
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'
}
}
}
repositories{
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.6.2' //error is here
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
And this is my error message:
Failed to resolve: com.android.support.appcompat-v7:26.1.0
Error:- Install repository and sync project.
Open file.
Show in Project Structure Dialog.
Even clicking on Install repository and sync project does absolutely nothing.
Add this inside your repositories block in your project level build.gradle file:
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
This is the best way to do it.
In your root level gradle.build use below
buildscript {
repositories {
mavenCentral()
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
mavenCentral()
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and in your gradle-wrapper.properties file change the wrapper version as below
distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip
also in your app level build.gradle make sure you are using 26 vesion as below
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.xxxx"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

Right version of the android google play services

I'm building an android app to store a text file in the google drive.According to my perspective, the code is OK. But when I put the app level dependency of the google play-services, it throws an error in the app level version dependency. Due to this reason, I cannot sync the gradle. I think the error is with the version numbers.
here is the play service dependency I put
"compile 'com.google.android.gms:play-services:8.4.0'"
And this is the dependency that shows as an error when I put the above dependency
"compile 'com.android.support:appcompat-v7:23.4.0'"
Here is my app level graddle
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.example.xxxxx.calllogtogoogledrive"
minSdkVersion 19
targetSdkVersion 23
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'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services:8.4.0'
}
Here is the project level gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Could you try to change your build.gradle like this;
allprojects {
repositories {
maven { url "http://jcenter.bintray.com" }
}
Remove jcenter() add this.

Gradle can't resolve any of my dependencies

For some reason gradle can't resolve any of my dependencies. This is an example:
Module:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.2"
defaultConfig {
applicationId "app.simplelogin"
minSdkVersion 15
targetSdkVersion 24
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'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.squareup.okhttp3:okhttp:3.0.1'
testCompile 'junit:junit:4.12'
}
Project:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
mavenCentral()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
When I try to sync or build, I get the following error:
Failed to resolve: com.squareup.okhttp3:okhttp:3.0.1
I get this same error message with every dependency I try to add - anyone know why?
You probably have switched on offline mode in the Gradle tool window of Android Studio. Switch off offline mode and it should work if you have internet connection.
