Android Studio can't find com.jakewharton:butterknife-compiler:5.1.2

I'm trying to build my Android Project but when I rebuild I receive this error message:
Could not find com.jakewharton:butterknife-compiler:5.1.2.
Searched in the following locations:

Can someone help me?

Your project :app is missing a butter knife reference. From the documentation this is what you are missing:
repositories {
mavenCentral()
}
Also, the version you are using 5.1.2 does not exists:
{ "errors" : [ {
"status" : 404,
"message" : "Could not find resource" } ] }
Try the following file:
apply plugin: 'com.android.application'
buildscript {
repositories {
google()
mavenCentral()
}
}
allprojects {
repositories {
google()
mavenCentral()
}

Android realm cannot resolve symbol SyncCredentials, SyncUser, ObjectServerError. But Realm, RealmObject.. classes are working fine

I have taken code from Realm objectServerExample.
SyncCredentials creds = SyncCredentials.usernamePassword(username, password, createUser);
SyncUser.Callback<SyncUser> callback = new SyncUser.Callback<SyncUser>() {
#Override
public void onSuccess(#Nonnull SyncUser user) {
progressDialog.dismiss();
onLoginSuccess();
}
#Override
public void onError(#Nonnull ObjectServerError error) {
progressDialog.dismiss();
String errorMsg;
switch (error.getErrorCode()) {
case UNKNOWN_ACCOUNT:
errorMsg = "Account does not exists.";
break;
case INVALID_CREDENTIALS:
errorMsg = "User name and password does not match";
break;
default:
errorMsg = error.toString();
}
onLoginFailed(errorMsg);
}
};
It says Cannot resolve symbol SyncCredentials
io.realm.Realm class is working.

Main goal is to connect Android app with realm object server on aws-ec2. It is working and can be accessed from browser.

Add
realm {
syncEnabled = true
}
in gradle (module:app) to use realm sync feature

butterKnife returns null when binding view (8.6.0)

When i'm trying to do this:
...
public class LoginActivity extends AppCompatActivity {
#BindView(R.id.login_form) View loginForm;
...
loginForm is getting null. I tried to follow other answers and nothing worked (this for example). I also did exactly what it said in the butterKnife configuration page and it didn't work. What am I doing wrong?

Probably, you forget to put this line:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_activity);
ButterKnife.bind(this);
...
}

In onCreate you have to call
ButterKnife.Bind(this)
before you use the views
Also add mavenCentral() to repositories in gradle
repositories {
jcenter()
mavenCentral()
}

No virtual method com_polidea_rxandroidble_internal_radio_RxBleRadioImpl$$Lambda$1_lambda$new$0()V

I am new in Android Developement and I try to implement Bluetooth LE features on my app.
I have some difficulties to run my android project with RXAndroidBLE.
This library use lambda and I am not able to make it run.
I have updated my gradle file:
apply plugin: 'com.android.application'

compile "com.polidea.rxandroidble:rxandroidble:1.1.0"
}
When I try to run the following code in my MainActivity, an error is displayed:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RxBleClient rxBleClient = RxBleClient.create(this);
Subscription scanSubscription = rxBleClient.scanBleDevices()
.subscribe(
rxBleScanResult -> {
// Process scan result here.
Log.e("DEVICE", rxBleScanResult.getBleDevice().getName());
},
throwable -> {
// Handle an error here.
}
);
// When done, just unsubscribe.
scanSubscription.unsubscribe();
}

I've no idea why it goes wrong.
If anyone could help me it would be great.
Thanks!

I finally found a solution by removing jackOptions.
Now it works like a charm.

Had this problem too. But just removing jackOptions didn't work. Had to add retrolambda to my project. My build gradle now looks like this :
apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'me.tatarka:gradle-retrolambda:3.3.1'
}
}
repositories {
mavenLocal()
}
android {
compileSdkVersion 24
buildToolsVersion "24.0.3"
defaultConfig {
applicationId "com.trump.islove"
minSdkVersion 18
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'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
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.polidea.rxandroidble:rxandroidble:1.1.0"
compile 'com.jakewharton:butterknife:8.4.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
testCompile 'junit:junit:4.12'
}

you must write to your build.gradle file:
apply plugin: 'me.tatarka.retrolambda'
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'me.tatarka:gradle-retrolambda:3.3.1'
}
}
