JNI实现Broadcast-创新互联

JNIEXPORT jint JNICALL Java_com_encrypt_EncryptActivity_cputExtra(JNIEnv *env,

        jobject, jobject mContext, jstring actionName, jobjectArray key,

        jobjectArray value) {

    //找到Intent类

    jclass intentClass = env->FindClass("android/content/Intent");

    if (intentClass == 0) {

        return 0;

    }

    jobject intent;

    jmethodID intentId;

    intentId = env->GetMethodID(intentClass, "", "()V");

    if (intentId) {

        intent = env->NewObject(intentClass, intentId);

    } else {

        return 0;

    }

    jmethodID setActionId = env->GetMethodID(intentClass, "setAction",

            "(Ljava/lang/String;)Landroid/content/Intent;");

    if (setActionId == 0) {

        return 0;

    }

    env->CallObjectMethod(intent, setActionId, actionName);

    jmethodID putExtraId = env->GetMethodID(intentClass, "putExtra",

            "(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;");

    if (putExtraId == 0) {

        return 0;

    }

    int size = env->GetArrayLength(key);

    int i = 0;

    for (i = 0; i < size; i++) {

        jstring keys = (jstring) env->GetObjectArrayElement(key, i);

        jstring values = (jstring) env->GetObjectArrayElement(value, i);

        env->CallObjectMethod(intent, putExtraId, keys, values);

    }

    if (mContext == 0) {

        return 0;

    }

    jclass cls_context = env->FindClass("android/content/Context");

    if (cls_context == 0) {

        return 0;

    }

    jmethodID sendBroadcastId = env->GetMethodID(cls_context, "sendBroadcast",

            "(Landroid/content/Intent;)V");

    if (sendBroadcastId == 0) {

        return 0;

    }

    env->CallVoidMethod(mContext, sendBroadcastId, intent);

    return 1;

}

申明:

public native static int cputExtra(Context mContext,

      String action, String[] key, String[] value);

加载库:

  static {

    System.loadLibrary("****");

  }

调用:

 String[] a = {"a","b"};

 String[] c = {"c","d"};

 cputExtra(this,"android.provider.telephony.SMS_RECEIVED", a, c);

接收端:

public class sendBroadcasttest extends BroadcastReceiver {

  @Override

  public void onReceive(Context context, Intent intent) {

    // TODO Auto-generated method stub

    String str = intent.getAction();

    String name = intent.getStringExtra("b");

    Log.i("aaaaa", "FirstReceiver: " + name);

  }

}

需要添加权限
