解决：短信添加录音附件，录音，没有录音时间限制，超出彩信最大限制也正常录音

【测试步骤】

短信添加录音附件，录音

【测试结果】

没有录音时间限制，超出彩信最大限制也正常录音

【预期结果】

应该有录音时间限制

首先分析是否因在彩信中没有没有在Intent中封装彩信剩余大小，定位到ComposeMessageActivity类的addAttachment（）方法中：

private void addAttachment(int type, boolean replace) {

// Calculate the size of the current slide if we're doing a replace so the

// slide size can optionally be used in computing how much room is left for an attachment.

int currentSlideSize = 0;

SlideshowModel slideShow = mWorkingMessage.getSlideshow();

if (replace && slideShow != null) {

WorkingMessage.removeThumbnailsFromCache(slideShow);

SlideModel slide = slideShow.get(0);

currentSlideSize = slide.getSlideSize();

}

switch (type) {

case AttachmentTypeSelectorAdapter.ADD_IMAGE:

MessageUtils.selectImage(this, REQUEST_CODE_ATTACH_IMAGE);

break;

case AttachmentTypeSelectorAdapter.TAKE_PICTURE: {

MessageUtils.capturePicture(this, REQUEST_CODE_TAKE_PICTURE);

break;

}

case AttachmentTypeSelectorAdapter.ADD_VIDEO:

MessageUtils.selectVideo(this, REQUEST_CODE_ATTACH_VIDEO);

break;

case AttachmentTypeSelectorAdapter.RECORD_VIDEO: {

long sizeLimit = computeAttachmentSizeLimit(slideShow, currentSlideSize);

if (sizeLimit > 0) {

MessageUtils.recordVideo(this, REQUEST_CODE_TAKE_VIDEO, sizeLimit);

} else {

Toast.makeText(this,

getString(R.string.message_too_big_for_video),

Toast.LENGTH_SHORT).show();

}

}

break;

case AttachmentTypeSelectorAdapter.ADD_SOUND:

MessageUtils.selectAudio(this, REQUEST_CODE_ATTACH_SOUND);

break;

case AttachmentTypeSelectorAdapter.RECORD_SOUND:

long sizeLimit = computeAttachmentSizeLimit(slideShow, currentSlideSize);

MessageUtils.recordSound(this, REQUEST_CODE_RECORD_SOUND, sizeLimit);

break;

case AttachmentTypeSelectorAdapter.ADD_SLIDESHOW:

editSlideshow();

break;

case AttachmentTypeSelectorAdapter.ADD_CONTACT_AS_TEXT:

pickContacts(MultiPickContactsActivity.MODE_INFO,

replace ? REQUEST_CODE_ATTACH_REPLACE_CONTACT_INFO

: REQUEST_CODE_ATTACH_ADD_CONTACT_INFO);

break;

case AttachmentTypeSelectorAdapter.ADD_CONTACT_AS_VCARD:

pickContacts(MultiPickContactsActivity.MODE_VCARD,

REQUEST_CODE_ATTACH_ADD_CONTACT_VCARD);

break;

default:

break;

}

}

从以上代码中发现，这里的Intent中已经封装了彩信剩余大小的控制，因此该问题进入录音机界面进行分析：

经过分析发现，录音机应用并没有从Intent中取出对录音文件大小的控制。

修改方法：LemediaRecorder类的onCreate中进行修改：

public void onCreate(Bundle icycle) {

super.onCreate(icycle);

stopRecorder();

mSharedPreferences = getSharedPreferences("storage_Path", Context.MODE_PRIVATE);

mPrefsStoragePathEditor = mSharedPreferences.edit();

mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

Intent i = getIntent();

if (i != null) {

intentRecorder = true;

final String EXTRA_MAX_BYTES

= android.provider.MediaStore.Audio.Media.EXTRA_MAX_BYTES;

mMaxFileSize = i.getLongExtra(EXTRA_MAX_BYTES, -1);

}

if (AUDIO_ANY.equals(mRequestedType) || ANY_ANY.equals(mRequestedType)) {

mRequestedType = AUDIO_AMR;

}

mPath = mSharedPreferences.getInt("path", mPath);

//mRequestedType = mSharedPreferences.getString("requestedType", mRequestedType);

mRequestedType = AUDIO_AMR;

//mFileType = mSharedPreferences.getInt("fileType", mFileType);

mFileType = 0;

mStoragePath = mSharedPreferences.getString("storagePath", mStoragePath);

if (!mWAVSupport && mRequestedType == AUDIO_WAVE_2CH_LPCM) {

mRequestedType = AUDIO_AMR;

mFileType = 0;

}

setContentView(R.layout.main);

mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

mRecorder = new Recorder();

mRecorder.setOnStateChangedListener(this);

mRemainingTimeCalculator = new RemainingTimeCalculator(LemediaRecorder.this);

PowerManager pm

= (PowerManager) getSystemService(Context.POWER_SERVICE);

mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,

"LemediaRecorder");

initResourceRefs();

mRecorderStop = false;

mDataExist = false;

setResult(RESULT_CANCELED);

registerExternalStorageListener();

if (icycle != null) {

Bundle recorderState = icycle.getBundle(RECORDER_STATE_KEY);

if (recorderState != null) {

mRecorder.restoreState(recorderState);

mSampleInterrupted = recorderState.getBoolean(SAMPLE_INTERRUPTED_KEY, false);

mMaxFileSize = recorderState.getLong(MAX_FILE_SIZE_KEY, -1);

int showAndExit = recorderState.getInt(DIALOG_STATE_KEY);

mLastFileName = recorderState.getString(LAST_FILE_NAME_KEY);

if (showAndExit != -1) showDialogAndExit(showAndExit == 1);

}

}

mTelephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

mPhoneStateListener = getPhoneStateListener();

String ssrRet = mAudioManager.getParameters("ssr");

if (ssrRet.contains("=true")) {

bSSRSupported = true;

} else {

bSSRSupported = false;

}

updateUi();

}

问题OK，搞定！
