Crash on theme Theme.AppCompat.Light.NoActionBar

It's crashed, i think maybe it's needed to set some attribute in my theme?

Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 6: TypedValue{t=0x2/d=0x7f040098 a=4 r=0x7f06003f} at android.content.res.TypedArray.getColorStateList(TypedArray.java:498) at android.widget.TextView.<init>(TextView.java:824) at android.widget.TextView.<init>(TextView.java:735) at android.support.v7.widget.AppCompatTextView.<init>(AppCompatTextView.java:76) at android.support.v7.widget.AppCompatTextView.<init>(AppCompatTextView.java:72) at android.support.v7.widget.AppCompatTextView.<init>(AppCompatTextView.java:68) at android.support.v7.widget.Toolbar.setTitle(Toolbar.java:754) at android.support.v7.widget.ToolbarWidgetWrapper.setTitleInt(ToolbarWidgetWrapper.java:261) at android.support.v7.widget.ToolbarWidgetWrapper.setWindowTitle(ToolbarWidgetWrapper.java:243) at android.support.v7.app.ToolbarActionBar.<init>(ToolbarActionBar.java:72) at android.support.v7.app.AppCompatDelegateImplV9.setSupportActionBar(AppCompatDelegateImplV9.java:217) at android.support.v7.app.AppCompatActivity.setSupportActionBar(AppCompatActivity.java:129) at com.nbsp.materialfilepicker.ui.FilePickerActivity.initToolbar(FilePickerActivity.java:109) at com.nbsp.materialfilepicker.ui.FilePickerActivity.onCreate(FilePickerActivity.java:61) at android.app.Activity.performCreate(Activity.java:6361) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1113) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2532) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2667)  at android.app.ActivityThread.-wrap11(ActivityThread.java)  at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1501)  at android.os.Handler.dispatchMessage(Handler.java:111)  at android.os.Looper.loop(Looper.java:207)  at android.app.ActivityThread.main(ActivityThread.java:5811)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:802)  at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:692)
