初始屏幕在某些设备上崩溃

Question

我为我的应用程序创建了一个启动屏幕，它运行良好，但是在其他设备上测试时，如nougat软件它崩溃我不知道为什么我将目标SDK从版本25更改为26，但它也崩溃 这里是我的Splash.java

package mediaclub.app.paymob; 

import android.content.Context; 
import android.content.Intent; 
import android.content.SharedPreferences; 
import android.os.Handler; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class Splash extends AppCompatActivity { 

    public static final String PREF_FILE_NAME = "mediaclub.app.paymob.preferences"; 
    public static final String KEY_BALANCE = "balance"; 
    public static final String KEY_MOBILE_NUMBER = "mobile_number"; 
    public static final String KEY_FIRST = "first_time"; 
    Boolean first; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_splash); 

     first = Boolean.valueOf(readFromPreferences(Splash.this, KEY_FIRST, "true")); 

     Runnable mRunnable; 
     Handler mHandler = new Handler(); 

//  if (!gps.canGetLocation()) { 
//   gps.showSettingsAlert(); 
//  } 

     try { 
      mRunnable = new Runnable() { 

       @Override 
       public void run() { 
        // TODO Auto-generated method stub 
        if (first) { 
         Intent i = new Intent(Splash.this, RegisterActivity.class); 
         startActivity(i); 
        } else { 
         Intent i = new Intent(Splash.this, SignInActivity.class); 
//     Intent i = new Intent(Splash.this, MainActivity.class); 
         startActivity(i); 
        } 
       } 
      }; 

      mHandler.postDelayed(mRunnable, 3 * 1000); 

     }catch (Exception e){ 
      Intent i = new Intent(Splash.this, SignInActivity.class); 
//     Intent i = new Intent(Splash.this, MainActivity.class); 
      startActivity(i); 

     } 
    } 

    public static void saveToPreferences(Context context, String preferenceName, String preferenceValue) { 

     SharedPreferences sharedPreferences = context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE); 
     SharedPreferences.Editor editor = sharedPreferences.edit(); 
     editor.putString(preferenceName, preferenceValue); 
     editor.apply(); 
    } 

    public static String readFromPreferences(Context context, String preferenceName, String defaultValue) { 
     SharedPreferences sharedPreferences = context.getSharedPreferences(PREF_FILE_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.getString(preferenceName, defaultValue); 
    } 
} 

，这是的build.gradle

buildscript { 
    repositories { 
     maven { url 'https://maven.fabric.io/public' } 
    } 

    dependencies { 
     classpath 'io.fabric.tools:gradle:1.+'

请有人帮我解决这个情况，希望这可能是够清楚
