使用Provider传输数据时程序强制Finish

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button addData = (Button) findViewById(R.id.add_data);
addData.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Uri uri = Uri.parse("content://com.example.databasetest.provider/book");
ContentValues values = new ContentValues();
values.put("name", "A Clash of Kings");
values.put("author", "George Martin");
values.put("pages", 1040);
values.put("price", 22.85);
Uri newUri = getContentResolver().insert(uri, values);
newId = newUri.getPathSegments().get(1);
}
});

            public class MyDatabaseHelper extends SQLiteOpenHelper {

public static final String CREATE_BOOK = "create table Book("
        + "id integer primary key autoincrement, "
        + "author text, "
        + "price real, "
        + "pages integer, "
        + "name text)";











                    public class MyDatabaseHelper extends SQLiteOpenHelper {

public static final String CREATE_BOOK = "create table Book("
        + "id integer primary key autoincrement, "
        + "author text, "
        + "price real, "
        + "pages integer, "
        + "name text)";

把错误日志贴出来啊，这样看不出来
