如何调用android的系统接口

1. Uri uri = Uri.parse("");
2. Intent it = new Intent(Intent.ACTION_VIEWuri);
3. startActivity(it);

1. Uri uri = Uri.parse("geo:38.-77.");
2. Intent it = new Intent(Intent.Action_VIEWuri);
3. startActivity(it);

1. Uri uri = Uri.parse("");
2. Intent it = new Intent(Intent.ACTION_VIEWURI);
3. startActivity(it);

1. Uri uri = Uri.parse("tel:xxxxxx");
2. Intent it = new Intent(Intent.ACTION_DIAL uri);
3. startActivity(it);

4. 1. Uri uri = Uri.parse("tel.xxxxxx");
2. Intent it =new Intent(Intent.ACTION_CALLuri);
3. 要运用这个必须在配置文件中加入

1. Intent it = new Intent(Intent.ACTION_VIEW);
2. it.putExtra("sms_body" "The SMS text");
3. it.setType("vnd.android-dir/mms-sms");
4. startActivity(it);

1. Uri uri = Uri.parse("smsto:03");
2. Intent it = new Intent(Intent.ACTION_SENDTO uri);
3. it.putExtra("sms_body" "The SMS text");
4. startActivity(it);

1. Uri uri = Uri.parse("content://media/external/images/media/23");
2. Intent it = new Intent(Intent.ACTION_SEND);
3. it.putExtra("sms_body" "some text");
4. it.putExtra(Intent.EXTRA_STREAM uri);
5. it.setType("image/png");
6. startActivity(it);

1.
2. Uri uri = Uri.parse("mailto:");
3. Intent it = new Intent(Intent.ACTION_SENDTO uri);
4. startActivity(it);

1. Intent it = new Intent(Intent.ACTION_SEND);
2. it.putExtra(Intent.EXTRA_EMAIL "");
3. it.putExtra(Intent.EXTRA_TEXT "The email body text");
4. it.setType("text/plain");
5. startActivity(Intent.createChooser(it "Choose Email Client"));

1. Intent it=new Intent(Intent.ACTION_SEND);
2. String[] tos={""};
3. String[] ccs={""};
4. it.putExtra(Intent.EXTRA_EMAIL tos);
5. it.putExtra(Intent.EXTRA_CC ccs);
6. it.putExtra(Intent.EXTRA_TEXT "The email body text");
7. it.putExtra(Intent.EXTRA_SUBJECT "The email subject text");
8. it.setType("message/rfc822");
9. startActivity(Intent.createChooser(it "Choose Email Client"));

1. Intent it = new Intent(Intent.ACTION_SEND);
2. it.putExtra(Intent.EXTRA_SUBJECT "The email subject text");
3. it.putExtra(Intent.EXTRA_STREAM "file:///sdcard/mysong.mp3");
4. sendIntent.setType("audio/mp3");
5. startActivity(Intent.createChooser(it "Choose Email Client"));

1.
2. Intent it = new Intent(Intent.ACTION_VIEW);
3. Uri uri = Uri.parse("file:///sdcard/song.mp3");
4. it.setDataAndType(uri "audio/mp3");
5. startActivity(it);

1. Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI "1");
2. Intent it = new Intent(Intent.ACTION_VIEW uri);
3. startActivity(it);

1. Uri uri = Uri.fromParts("package" strPackageName null);
2. Intent it = new Intent(Intent.ACTION_DELETE uri);
3. startActivity(it);

Intent intent=newIntent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(People.CONTENT_URI);
startActivity(intent);

Uri personUri=ContentUris.withAppendedId(People.CONTENT_URI info.id);//info.id联系人ID
Intent intent=newIntent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(personUri);
startActivity(intent);

Intent intent=newIntent();
intent.setDataAndType(Uri.parse(file:///sdcard/newmopclient.apk)"application/vnd.android.package-archive");
startActivity(intent);

public static final String MIME_TYPE_IMAGE_JPEG = "image/*";
public static final int ACTIVITY_GET_IMAGE = 0;

Intent getImage = new Intent(Intent.ACTION_GET_CONTENT);
getImage.addCategory(Intent.CATEGORY_OPENABLE);
getImage.setType(MIME_TYPE_IMAGE_JPEG);
startActivityForResult(getImage ACTIVITY_GET_IMAGE);

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
time = Calendar.getInstance().getTimeInMillis();
intent.putExtra(MediaStore.EXTRA_OUTPUT Uri.fromFile(new File(Environment
.getExternalStorageDirectory().getAbsolutePath()+"/tucue" time + ".jpg")));
startActivityForResult(intent ACTIVITY_GET_CAMERA_IMAGE);

@paramapkname apk名称
publicvoidsetupAPK(String apkname){
String fileName=Environment.getExternalStorageDirectory()+"/"+apkname;
Intent intent=newIntent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(newFile(fileName))"application/vnd.android.package-archive");
mService.startActivity(intent);
}
