Upgrade API Level in Android Studio

Question

I've encountered some issues when I try to update my app to Marshmallow 6.0.1. I was previously working on 5.1.1 and I made some room for updating Android so I made sure to make it compatible with APIs 21-24. Right now, 6.0.1 runs on API 23 but for some reason the app crashes when it starts. I am running the latest Android Studio, 3.0.1 and I only want it to work on Android M. I have two modules, one of them is an external library for the camera. I share my gradle settings:

For the 'app' module is:

apply plugin: 'com.android.application'

 android {
    compileSdkVersion 24
    buildToolsVersion '26.0.2'
    useLibrary  'org.apache.http.legacy'


    defaultConfig {
        applicationId "XXXXXXXXX"
        minSdkVersion 21
        targetSdkVersion 24
        versionCode 332
        versionName "1.7.3d"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    lintOptions{
        disable 'MissingTranslation'
    }
 }
  repositories {
     jcenter()
     maven { url "https://dl.bintray.com/drummer-aidan/maven" }
  }

 dependencies {
    compile project(':cam-library')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:support-v13:25.3.0'
    compile 'com.android.support:appcompat-v7:25.3.0'
    compile 'com.android.support:design:25.3.0'
    compile 'com.google.code.gson:gson:2.7'
    compile 'com.android.volley:volley:1.0.0'
    compile 'org.apache.httpcomponents:httpmime:4.2.3'
    compile 'com.jcraft:jsch:0.1.54'
    compile 'com.jcraft:jzlib:1.1.3'}

The other one, the Follestad material camera module:

 apply plugin: 'com.android.library'

 ext {
    PUBLISH_GROUP_ID = 'com.afollestad'
    PUBLISH_ARTIFACT_ID = 'material-camera'
    PUBLISH_VERSION = '0.3.2'
    PUBLISH_VERSION_CODE = 21
    SUPPORT_LIB_VERSION = '25.3.0'
    VIDEO_PLAYER_VERSION = '0.2.12'
    MD_VERSION = '0.9.0.1'
    TARGET_SDK = 24
    BUILD_TOOLS = "24.0.1"
 }

android {
    compileSdkVersion TARGET_SDK
    buildToolsVersion BUILD_TOOLS

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion TARGET_SDK
        versionCode PUBLISH_VERSION_CODE
        versionName PUBLISH_VERSION
    }
    lintOptions {
        abortOnError false
        checkReleaseBuilds false
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    buildToolsVersion '25.0.0'
 }

repositories {
    jcenter()
    maven { url "https://dl.bintray.com/drummer-aidan/maven" }
 }

dependencies {
    compile "com.android.support:appcompat-v7:$SUPPORT_LIB_VERSION"
    compile "com.afollestad:easyvideoplayer:$VIDEO_PLAYER_VERSION"
    compile "com.afollestad.material-dialogs:core:$MD_VERSION"
    compile 'com.android.support:recyclerview-v7:25.3.0'
 } 

//apply from: 'https://raw.githubusercontent.com/afollestad/aidanfollestad.com/master/android-lib-release.gradle'

And lastly the gradle version settings:

    // 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:3.0.1'

        // 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
}

What's wrong with this and why did it work on 5.1.1 and not on 6.0.1?

EDIT: This is the log

Answer 1

 call the askForMarshmallowPermissions method inside splash screen on create method. to grant danger premissions at run time you have to added External store read and camera premission. Add premissions in Manifest.xml 

 <uses-permission
        android:name="android.permission.CAMERA"
        android:required="false" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

askForMarshmallowPermissions(); call method in onCreate()

 private void askForMarshmallowPermissions() {
        List<String> permissionsNeeded = new ArrayList<String>();

        final List<String> permissionsList = new ArrayList<String>();


        if (!addPermission(permissionsList, android.Manifest.permission.WRITE_EXTERNAL_STORAGE))
            permissionsNeeded.add("Write to storage");

        if (!addPermission(permissionsList, Manifest.permission.CAMERA))
            permissionsNeeded.add("Camera");

        if (permissionsList.size() > 0) {
            if (permissionsNeeded.size() > 0) {
                // Need Rationale
                String message = "You need to grant access to " + permissionsNeeded.get(0);
                for (int i = 1; i < permissionsNeeded.size(); i++)
                    message = message + ", " + permissionsNeeded.get(i);
                showMessageOKCancel(message,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                ActivityCompat.requestPermissions(SplashScreen.this,
                                        permissionsList.toArray(new String[permissionsList.size()]),
                                        CommonUtils.REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
                            }
                        });
                return;
            }
            ActivityCompat.requestPermissions(SplashScreen.this, permissionsList.toArray(new String[permissionsList.size()]),
                    CommonUtils.REQUEST_CODE_ASK_MULTIPLE_PERMISSIONS);
            return;
        }
        callAfterPermission();


    }

       private boolean addPermission(List<String> permissionsList, String permission) {
        if (ContextCompat.checkSelfPermission(SplashScreen.this, permission) != PackageManager.PERMISSION_GRANTED) {
            permissionsList.add(permission);
            // Check for Rationale Option
            if (!ActivityCompat.shouldShowRequestPermissionRationale(SplashScreen.this, permission))
                return false;
        }
        return true;
    }


        private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
        new AlertDialog.Builder(SplashScreen.this)
                .setMessage(message)
                .setPositiveButton("OK", okListener)
                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        CommonUtils.showAlertDialogWithFinishActivity(SplashScreen.this,
                                "Please grant all required permissions to " +
                                        "continue running the app.",

                    }
                })
                .create()
