1、申请权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />

java

private static final String[] authBaseArr = {//申请类型Manifest.permission.CAMERA,Manifest.permission.WRITE_EXTERNAL_STORAGE
};
private static final int authBaseRequestCode = 1;

private boolean hasBasePhoneAuth() {PackageManager pm = getPackageManager();for (String auth : authBaseArr) {if (pm.checkPermission(auth, getPackageName()) != PackageManager.PERMISSION_GRANTED) {return false;}}return true;
}private void initNavi() {// 申请权限if (android.os.Build.VERSION.SDK_INT >= 23) {if (!hasBasePhoneAuth()) {this.requestPermissions(authBaseArr, authBaseRequestCode);return;}}
}

2、开始起调相机

private static final int REQUEST_PERMISSION_CODE = 101;
private String SAVE_PIC_PATH = Environment.getExternalStorageState().equalsIgnoreCase(Environment.MEDIA_MOUNTED)? Environment.getExternalStorageDirectory().getAbsolutePath() : "/mnt/sdcard";//private String SAVE_REAL_PATH = SAVE_PIC_PATH + "/good/savePic";//保存的确
private String ends = "";

                Intent intent = new Intent();// 指定开启系统相机的Actionintent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);//图片intent.addCategory(Intent.CATEGORY_DEFAULT);//图片
//                intent.setAction("android.media.action.VIDEO_CAPTURE");//视频
//                intent.addCategory("android.intent.category.DEFAULT");//视频// 根据文件地址创建文件String subForder = SAVE_REAL_PATH;File foder = new File(subForder);if (!foder.exists()) foder.mkdirs();File file = new File(subForder, System.currentTimeMillis() + ".png");//图片
//                File file = new File(subForder, System.currentTimeMillis() + ".mp4");//视频ends = file.getPath();if (file.exists()) {file.delete();}// 把文件地址转换成Uri格式Uri uri = Uri.fromFile(file);// 设置系统相机拍摄照片完成后图片文件的存放地址intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);startActivityForResult(intent, REQUEST_PERMISSION_CODE);

3、保存图片

调用EXTRA_OUTPUT时，已经保存了图片到文件夹——只是相册不可见

如需相册可见，自定义保存即可

    public void saveBitmapFile(Bitmap bitmap) {File file = new File(ends);//将要保存图片的路径try {BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(file));bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bos);bos.flush();bos.close();
//            FileOutputStream fos = new FileOutputStream(file);
//            bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
//            fos.flush();
//            fos.close();Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);Uri uri = Uri.fromFile(file);intent.setData(uri);this.sendBroadcast(intent);} catch (IOException e) {e.printStackTrace();}}

 录音报错：startRecording() called on an uninitialized AudioRecord.

解决方法如下 

录音权限

    <uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT" />  
    <uses-permission android:name="android.permission.CAPTURE_VIDEO_OUTPUT"/>  
    <uses-permission android:name="android.permission.RECORD_AUDIO" />  
    <uses-sdk  
        android:minSdkVersion="19"  
        android:targetSdkVersion="19" />  
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
 

把apk重新签名为系统应用。

(1)在AndroidManifest.xml文件的application标签中，增加配置：android:sharedUserId="android.uid.system"

 

    packagingOptions{exclude 'META-INF/DEPENDENCIES'exclude 'META-INF/NOTICE'exclude 'META-INF/LICENSE'exclude 'AndroidManifest.xml'
//        exclude 'META-INF/LICENSE.txt'
//        exclude 'META-INF/NOTICE.txt'}
