广播的设置

public class BootBroadcastReceiver extends BroadcastReceiver { public BootBroadcastReceiver(){ } String ACTION = "android.intent.action.BOOT_COMPLETED"; @Override public void onReceive(Context context, Intent intent) { if (intent.getAction().equals(ACTION)){ Intent sayHelloIntent=new Intent(context,MainActivity.class); sayHelloIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // context.startActivity(sayHelloIntent); Toast.makeText(context,"重启成功",Toast.LENGTH_SHORT).show(); } } } public class DatabaseAdapter { private DatabaseHelper dbHelper; public DatabaseAdapter(Context context){dbHelper=new DatabaseHelper(context);} } class DatabaseHelper extends SQLiteOpenHelper { private static String DB_NAME = "track.db"; //表名 public static String TABLE_TRACK = "track"; public static String TABLE_TRACK_DETAIL = "track_detail"; //字段 public static String ID = "_id"; //跟踪表 public static String TRACK_NAME = "track_name"; public static String CREATE_DATE = "create_date"; public static String START_LOC = "start_loc"; public static String END_LOC = "end_loc"; //明细表 public static String TID = "tid";//线路的ID public static String LAT = "lat";//维度 public static String LNG = "lng";//经度 private static String CREATE_TABLE_TRACK = "create table track(_id integer primary key autoincrement,track_name text,create_date text,start_loc text,end_loc text)"; private static String CREATE_TABLE_TRACK_DETAIL = "create table track_detail(_id integer primary key autoincrement,tid integer not null,lat real,lng real)"; private static int VERSION = 1; public DatabaseHelper(Context context) { super(context, DB_NAME, null, VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL(CREATE_TABLE_TRACK); db.execSQL(CREATE_TABLE_TRACK_DETAIL); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { if (newVersion > oldVersion) { db.execSQL("drop table if exists track"); db.execSQL("drop table if exists track_detail"); db.execSQL(CREATE_TABLE_TRACK); db.execSQL(CREATE_TABLE_TRACK_DETAIL); } }

Bmob的权限设置及相关

allprojects { repositories { google() jcenter() maven { url "https://raw.github.com/bmob/bmob-android-sdk/master" } } } //build.gradle中的是设置 implementation files('libs/BaiduLBS_Android.jar') implementation 'cn.bmob.android:bmob-sdk:3.7.3-rc1' implementation "io.reactivex.rxjava2:rxjava:2.2.2" implementation 'io.reactivex.rxjava2:rxandroid:2.1.0' implementation 'com.squareup.okio:okio:2.1.0' implementation 'com.google.code.gson:gson:2.8.5' implementation 'com.squareup.okhttp3:okhttp:3.12.0'

短信识别
