Throwing a Fatal error

[dkostins]

I just copied and pasted the code and changed the links around but can't get the example working, and like it is throwing a really strange error.
I think here is the code in question I belive:
private void loadIpCam() {
Mjpeg.newInstance()
.credential(getPreference("demo"), getPreference("nxwitness"))
.open(getPreference("http://demo.networkoptix.com:7001/media/5bafc0e9-56be-97f8-5034-45a50cecf3d8.mpjpeg"), TIMEOUT)
.subscribe(
inputStream -> {
mjpegView.setSource(inputStream);
mjpegView.setDisplayMode(calculateDisplayMode());
mjpegView.showFps(true);
},
throwable -> {
Log.e(getClass().getSimpleName(), "mjpeg error", throwable);
Toast.makeText(this, "Error", Toast.LENGTH_LONG).show();
});
}
and it throws this error in Android Studios, it looks like there is dependency missing somewhere or something?
Caused by: java.lang.NoSuchMethodError: No static method com_github_niqdev_mjpeg_Mjpeg$$Lambda$1_lambda$connect$0(Lcom/github/niqdev/mjpeg/Mjpeg;Ljava/lang/String;)Lrx/Observable; in class Lcom/github/niqdev/mjpeg/Mjpeg; or its super classes (declaration of 'com.github.niqdev.mjpeg.Mjpeg' appears in /data/app/danmax.javaalexa-2/base.apk)

I think your copy and paste is wrong, getPreference read from the preferences, try something like this. Please let me know if that was the issue or there is something else.
Thanks

Mjpeg.newInstance()
  .credential("demo", "nxwitness")
  .open("http://demo.networkoptix.com:7001/media/5bafc0e9-56be-97f8-5034-45a50cecf3d8.mpjpeg", TIMEOUT)
  .subscribe(
    inputStream -> {
      mjpegView.setSource(inputStream);
      mjpegView.setDisplayMode(calculateDisplayMode());
      mjpegView.showFps(true);
    },
    throwable -> {
      Log.e(getClass().getSimpleName(), "mjpeg error", throwable);
      Toast.makeText(this, "Error", Toast.LENGTH_LONG).show();
  });

Uhm, just a question, have you tried the example from google play? Is it working?

[dkostins]

What's the name on Google play, but yeah I haven't .

[niqdev]

Have a look the README,
Anyway I tried, but i think the problem is the format mpjpeg (motion jpeg), the library supports only mjpeg.
If you try the demo app you should get an error similar to

java.io.FileNotFoundException: http://demo.networkoptix.com:7001/media/5bafc0e9-56be-97f8-5034-45a50cecf3d8.mpjpeg
 at com.android.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:238)

That is like a 404 i.e. Not Found, in this case not supported I guess

[dkostins]

Dang that is not exactly my problem because I tried to do a wrong url to get a 404 but it still threw that original error .Granted doesn't matter since not of the formats provided by the API I'm using has the correct format for your program . Thanks anyway :)

[spurd0]

Having same problem. Just imported your lib to new project & got same exception. App from play market works well.

[spurd0]

All right, solved it by adding:
classpath 'com.android.tools.build:gradle:2.3.1'
classpath 'me.tatarka:gradle-retrolambda:3.6.1'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
to project's build gradle

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'com.neenbedankt.android-apt'

To module gradle

& adding your`s bintray.gradle

[niqdev]

Sorry for the late response, glad you found a solution. Thanks for sharing

[ulaserdegor]

@spurd0 hi. your solution not work for me. Can you help me?

[spurd0]

@ulaserdegor what error have you got? Please share your build.gradle for app & project.

[ulaserdegor]

@spurd0 same your error. my gradle files like yours.
i using java 1.8 and sdk 27

[spurd0]

@ulaserdegor

Here is my project's build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath 'me.tatarka:gradle-retrolambda:3.6.1'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.github.dcendents:android-maven-gradle-plugin:1.5'
        classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.7.3'
    }
}

allprojects {
    group = 'com.github.niqdev'
    version = '1.1.0'

    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Pay attention to group = 'com.github.niqdev', as i remembered i got error because i didn't have it. Also i used 25 sdk.
