Answer 1

Это ошибка из вашего LogCat:

FATAL EXCEPTION: main 
09-02 04:29:32.066: E/AndroidRuntime(781): java.lang.RuntimeException: Unable to start activity ComponentInfo{hellog.diwesh.NugaBest/helog.diwesh.NugaBest.BTSmartSlavemodule}: android.util.AndroidRuntimeException: requestFeature() must be called before adding content 

Answer 2

Несколько вопросов здесь:

09-02 04:29:31.766: W/System.err(781): java.io.IOException: open failed: EROFS (Read-only file system) 
09-02 04:29:31.776: W/System.err(781): at java.io.File.createNewFile(File.java:948) 
09-02 04:29:31.785: W/System.err(781): at helog.diwesh.NugaBest.BTSmartSlavemodule.onCreate(BTSmartSlavemodule.java:118) 

В BTSmartSlavemodule.java строке 118 вы пытаетесь для создания нового файла в файловой системе только для чтения.

09-02 04:29:32.066: E/AndroidRuntime(781): Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content 
09-02 04:29:32.066: E/AndroidRuntime(781): at com.android.internal.policy.impl.PhoneWindow.requestFeature(PhoneWindow.java:226) 
09-02 04:29:32.066: E/AndroidRuntime(781): at android.app.Activity.requestWindowFeature(Activity.java:3264) 
09-02 04:29:32.066: E/AndroidRuntime(781): at helog.diwesh.NugaBest.BTSmartSlavemodule.onCreate(BTSmartSlavemodule.java:141) 

В строке 141 того же файла, который вы пытаетесь вызвать requestWindowFeature() после вызова setContentView(). Вам необходимо установить функции окна до setContentView().

Answer 3

Вы называете requestFeature() не в нужном месте ... попытаться вызвать этот метод перед setContentView(R.layout.activity)

Answer 4

Причина этой ошибки:

09-02 04:29:32.066: E/AndroidRuntime(781): Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content 

И это причина произошло на:

09-02 04:29:31.785: W/System.err(781): at helog.diwesh.NugaBest.BTSmartSlavemodule.onCreate(BTSmartSlavemodule.java:118) 

Где вы размещаете код. requestWindowFeature(). Чтобы избежать этой причины вы должны поместить этот код перед setContentView(R.layout.your_layout);

Answer 5

Я думаю, что вы пытаетесь создать файл на SDCard, но вы не указали разрешения писать внешнее хранилище в файле манифеста

Добавьте эту строку manifest.xml файл

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